Composite particles of Ba0.9La0.1FeO3 (BLF) and SnO2 have been designed to amplify the receptor function of semiconductor gas sensor and achieve high sensitivity toward volatile organic compound gases. During operation, the sensor was driven under double-pulse mode (DP-mode) that includes high-temperature preheating. According to the temperature programmed desorption measurement, oxygen desorption from the BLF-SnO2 composite occurred at lower temperatures than that from SnO2, and the amount of oxygen desorption was also larger. Under the DP-mode, the electrical resistance of BLF-SnO2 was significantly higher than that of SnO2, because BLF acted as an oxygen supplier to increase effective oxygen concentration in the sensing layer. In addition, temperature programmed reaction measurement revealed that ethanol desorbed from BLF, and that the total amount of ethanol desorption and combustion on BLF-SnO2 was larger than that on SnO2. Thus, the sensor response to ethanol based on ethanol combustion reaction was enhanced when using BLF-SnO2 under the DP-mode, especially the sensor response to 1 ppm ethanol showed 143 at the preheating and measurement temperatures of 400 °C and 250 °C, respectively. This enhanced response was attributed to the condensation of oxygen and ethanol under the DP-mode, with BLF playing the role of oxygen and ethanol provider. Thus, compositing BLF with SnO2 significantly amplified the receptor function of the sensing material, and such materials design could lead to improved sensitivity.

Lowering the volatile organic compound (VOC) gas detection limit toward the ppt level on a resistive-type semiconductor gas sensor was achieved by combining the material and sensor-driven designs. We fabricated Pd-SnO2 clustered nanoparticles, a material that is highly sensitive to VOC gas, on a microsensor device with a double-pulse-driven mode. This mode was involved in switching the heater-on periods at high-temperature preheating and measurement phases and the rest phase during a heater-off period between preheating and measurement phases. The electrical resistance in synthetic air and the sensor response to toluene increased as preheating temperatures increased because of an increase in the amount of O2– adsorbed on the particle surface. In addition, extending the rest time between the preheating and measurement phases significantly improved the sensor response to toluene. According to the relationship between the sensor response and toluene concentration, we improved the lower detection limit for toluene gas to below 10 ppt, with preheating and measurement temperatures at 400 and 250 °C, respectively, and rest time at 100 s. Therefore, the combination of the material and sensor-driven designs may play a key role in improving the sensor performance.

To improve the sensing properties toward volatile organic compound gases, a preheating process was introduced in a miniature pulse-driven semiconductor gas sensor, using SnO2 nanoparticles. The miniature sensor went through a short preheating span at a high temperature before being cooled and then experienced a measurement span under heating; this is the double-pulse-driven mode. This operating profile resulted in the modification of the surface conditions of naked SnO2 nanoparticles to facilitate the adsorption of O2– and ethanol-based adsorbates. Temperature-programmed reaction measurement results show that ethanol gas was adsorbed onto the SnO2 surface at 30 °C, and the adsorption amount of ethanol and its byproducts was increased after ethanol exposure at high temperatures followed by cooling. The electrical resistance of the sensor in synthetic air increased as the preheating temperature increased. The sensor responses, Si and Se, to 1 ppm ethanol at 250 °C were enhanced by introducing the preheating process; Si values at 250 °C with and without preheating at 300 °C are 40 and 15, respectively. The obtained improvements were attributed to an increase in O2– adsorption onto the SnO2 surface during the preheating phase. During the cooling phases, the adsorption of ethanol-based molecules onto the SnO2 surface and their condensation in the sensing layer contributed to the enhanced performance. In addition, the double-pulse-driven mode improves the recovery speed in the electrical resistance after gas detection. These improvements made in the sensing properties of the double-pulse-driven semiconductor gas sensors provide desirable advantages for healthcare and medical devices.

Improvement of gas selectivity, especially among volatile organic compound (VOC) gases, was attempted by introducing pulse-driven modes in semiconductor gas sensors. The SnO2 microsensor was fabricated on a miniature sensor device constructed with a microheater and electrode. The gas-sensing properties were evaluated under a pulse-driven mode by switching the heater on and off. According to density functional theory calculations and temperature-programmed reaction measurements, toluene molecule, which is one of the VOC gases, was adsorbed on the SnO2 surface by van der Waals forces. The conventional sensor response, Se, defined as the change in the electrical resistance in air and target gas atmosphere, to toluene was four and eight times greater than that to CO and H2, respectively. Moreover, the newly proposed sensor response, Sp, defined as the change in the electrical resistance of the device in the target gas atmosphere during the heater-on period, to toluene was 33 and 29 times greater than that to CO and H2, respectively. This significant difference in the Sp to toluene was caused by the combustion reaction of condensed toluene within the sensing layer. Accordingly, the pulse-driven mode of the semiconductor gas sensor can be exploited to improve the gas selectivity of VOC gases based on these newly defined sensor response measures.

In this study, the influence of the oxygen partial pressures (PO2) on the sensor response to H2 of SnO2 resistive-type gas sensors was evaluated under various humid atmospheres. SnO2 nanoparticles of 8–15 nm in diameter were synthesized using a hydrothermal technique followed by calcination at 600°C. Additionally, a large amount of pores with diameters greater than 10 nm was confirmed in the nanoparticles. The electrical resistance at 350°C was decreased with decreasing the PO2, and the electrical resistance in the presence of 10 ppm H2 was much smaller than that in the absence of H2 in both dry and humid atmospheres regardless of the PO2. Furthermore, the sensor response to 10 ppm H2 at 350°C increased with decreasing PO2 in both dry and humid atmospheres. Thus, decreasing the amount of oxygen adsorption enhanced the effect of rooted hydroxyl formation on the SnO2 surface through a combustion reaction between H2 and adsorbed oxygen and improved the sensor response to H2. These results are important for understanding the fundamental mechanisms of gas detection and for the material surface design of highly sensitive resistive-type semiconductor gas sensors.

Improvements in the responses of semiconductor gas sensors and reductions in their detection limits toward volatile organic compounds (VOCs) are required in order to facilitate the simple detection of diseases, such as cancer, through human-breath analysis. In this study, we introduce a heater-switching, pulse-driven, micro gas sensor composed of a microheater and a sensor electrode fabricated with Pd-SnO2-clustered nanoparticles as the sensing material. The sensor was repeatedly heated and allowed to cool by the application of voltage to the microheater; the VOC gases penetrate into the interior of the sensing layer during its unheated state. Consequently, the utility factor of the pulse-driven sensor was greater than that of a conventional, continuously heated sensor. As a result, the response of the sensor to toluene was enhanced; indeed, the sensor responded to toluene at levels of 1 ppb. In addition, according to the relationship between its response and concentration of toluene, the pulse-driven sensor in this report can detect toluene at concentrations of 200 ppt and even lower. Therefore, the combination of a pulse-driven microheater and a suitable material designed to detect toluene resulted in improved sensor response, and facilitated ppt-level toluene detection. This sensor may play a key role in the development of medical diagnoses based on human breath.

Fabrication of a transparent film composed of a barium titanate (BaTiO3) and poly(methyl methacrylate) (PMMA) matrix is reported to expand the application field for composite films such as displays and touch panel screens. BaTiO3 nanoparticles are synthesized by sol–gel route with dispersion carried out in 2-methoxyethanol. The synthesized nanoparticles are 10 nm in size and are highly dispersed in the solvent. The surfaces of the obtained nanoparticles are modified by treatment with titanium isopropoxide and by using two silane coupling agents: n-decyltrimethoxysilane and 3-(triethoxysilyl)propyl methacrylate. The surface-modified BaTiO3 nanoparticles were then added to a sample of methyl methacrylate to obtain a transparent BaTiO3 dispersion. Transparent BaTiO3/PMMA nanocomposite films (sheet type, thickness of 150 μm) are obtained by the polymerization of the BaTiO3/MMA dispersion via heat treatment and by using a polymerization initiator. The visual transparency of the BaTiO3/PMMA film is comparable to that of the original PMMA film. Additionally, no difference in the transparency of the BaTiO3/PMMA films is observed when the BaTiO3 weight ratio is varied between 5% and 33%. The dielectric constant of the nanocomposite film improved from 4.6 (PMMA only) to 7.1 by incorporating 10 wt % of BaTiO3. Such improvement in the dielectric properties, while maintaining the transparency, flexibility, and workability of PMMA films, allows the expansion of the fields of functional ceramics and polymers.

Selectivity is an important parameter of resistivetype gas sensors that use metal oxides. In this study, a highly selective toluene sensor is prepared using highly dispersed goldnanoparticle-loaded zinc oxide nanoparticles (Au-ZnO NPs). Au-ZnO NPs are synthesized by coprecipitation and calcination at 400 °C with Au loadings of 0.15, 0.5, and 1.5 mol %. The Au NPs on ZnO are about 2−4 nm in size, and exist in a metallic state. Porous gas-sensing layers are fabricated by screen printing. The responses of the sensor to 200 ppm hydrogen, 200 ppm carbon monoxide, 100 ppm ethanol, 100 ppm acetaldehyde, 100 ppm acetone, and 100 ppm toluene are evaluated at 377 °C in a dry atmosphere. The sensor response of 0.15 mol % Au-ZnO NPs to toluene is about 92, whereas its sensor responses to other combustible gases are less than 7. Such selective toluene detection is probably caused by the utilization efficiency of the gas-sensing layer. Gas diffusivity into the sensing layer of Au-ZnO NPs is lowered by the catalytic oxidation of combustible gases during their diffusion through the layer. The present approach is an effective way to improve the selectivity of resistive-type gas sensors.

The type and amounts of oxygen adsorption species at various atmospheric humidity levels are important factors in improving the sensitivity to combustible gases and stability to humidity changes of SnO2-based resistive-type gas sensors. We investigated the effect of antimony (Sb) doping of SnO2 nanoparticles on the stability of the sensitivity to humidity changes and oxygen adsorption species under humid atmosphere. No significant degradation of the sensitivity to hydrogen of Sb-SnO2 sensors was observed between 16 and 96 RH%, while an undoped SnO2 sensor showed gradually ecreasing responses with increasing humidity. An evaluation of oxygen adsorption species under humid atmosphere showed a transition from O2− to O− with increasing humidity from 16 to 96 RH%. However, the O2− adsorption sites were maintained on the surfaces of the Sb- SnO2, even as the humidity increased. Moreover, the extent of oxygen adsorption on the Sb-SnO2 was not obviously changed with increasing humidity. These results indicate that Sb atoms function as hydroxyl absorbers and also generate O2− adsorption sites in their vicinity. Additionally, Pd loading on the Sb-SnO2 further enhanced the sensor response under humid atmosphere, while maintaining the stability to humidity changes. Therefore, we successfully imparted stability to the sensitivity of SnO2 nanoparticles during humidity changes, representing an important improvement with applications to the development of high performance, practical, resistive-type gas sensors.

As a typical toxic and hazardous industrial gas, n-butanol poses a potential threat to production safety and human health. It is essential to develop advanced sensors for effectively and reliably detecting n-butanol gas. Herein, hierarchical Au@Fe2O3-SnO2 core-shell nanotubes were prepared and used as functional materials for n-butanol gas sensing. The as-synthesized composites exhibit tube morphology with nanostructures of inner α-Fe2O3 1D nanotubes and outer grown SnO2 films, and Au nanoparticles (NPs) anchored on the surfaces. Au@Fe2O3-SnO2 core-shell nanotubes present high response toward n-butanol compared with pure α-Fe2O3 and Fe2O3-SnO2, and the proportions of Sn and Au were further optimized. The Au2FeSn5 possesses the optimal gas sensing properties both in the relatively dry and humid atmospheres. At the optimum working temperature of 240 ℃ (∼25% RH, ∼22 ℃), Au2FeSn5 sensor presents high response of 45.0 toward 100 ppm n-butanol, fast response/recovery time of 10/5 s, excellent linearity in the concentration range of 0.02–1000 ppm, low theory limitation of detection (LOD) of 2.2 ppb and good reproducibility and stability. The possible sensing enhancement mechanism was proposed from the point of views of gas adsorption and electron transfer. The heterojunctions between two oxides and the sensitization of Au NPs could contribute to the sensitivity to n-butanol detection.

The sensing properties of WO3-based gas sensors were evaluated at an operating temperature of 150 °C in the presence of different volatile organic compounds (VOCs). Simultaneously to the sensing tests, operando diffuse-reflectance infrared Fourier transform spectra were acquired. Remarkably, no CO2 generation was observed under gas exposure for any of the target VOCs. Catalytic combustion properties of the WO3 toward acetone and ethanol at temperatures from 150 to 400 °C, both in dry and humid atmospheres, were additionally performed. Such measurements confirmed that no combustion occurred for ethanol (up to at least 300 °C) while it became detectable for acetone only starting from 250 °C. The reaction products are acetaldehyde and acetate in the case of ethanol exposure and acetate and formate in the case of acetone exposure. The oxidation catalytic effect of WO3 was confirmed for both toluene, where benzaldehyde and benzoate modes were observed, and acetylene (where acetaldehyde and ethenol were detected). The systematic absence of CO2 as a product and the identification of oxidized species are the basis of the proposed reaction mechanisms.

Au decorated ZnO/ZnS/SnO2 nanostructures were prepared and used as sensing materials for cyclohexanone gas detection. Ternary ZnO/ZnS/SnO2 nanostructures were fabricated after hydrothermal method, sulfuration and calcination at a specific temperature. The achieved heterostructures are in the shape of nanoflower and then decorated with different amounts of Au nanoparticles (NPs). The results of gas sensing measurements demonstrate that construction of heterojunctions between components and functionalization with Au NPs could remarkably enhance the gas sensing performance toward cyclohexanone gas. Especially, Au2@ZnO/ZnS/SnO2 gas sensor exhibits the highest response (497–100 ppm), fast response/recovery speed (1/50 s), low theoretic limit of detection (1.1 ppb) and better selectivity (Scyc./Sother > 15.2) at 260 ℃, 25% RH (∼24 ℃). The details of heterojunctions between the three components and spillover effect of Au NPs-related sensitization mechanism are discussed finally.

We characterized the materials, confirmed the morphology of hollow microtubes and structure of the heterojunctions, and analyzed the effect of components and Pd NPs loading on the gas sensing performance. In gas sensing measurements, the Pd@Co3O4/In2O3 (PdCoIn-2) sensor shows high responses (21.5/16.4, 1 ppm), low limit of detections (LODs, 0.02/0.06 ppb), with fast response and recovery times (1 and 4 s/1 and 3 s) toward toluene under 54 %/95 % RH. In addition, PdCoIn-2 sensor also exhibits excellent selectivity, repeatability and long-term stability. Finally, based on the structure of this material, the enhanced sensing mechanism of PdCoIn-2 for toluene detection is discussed in depth.

Metal-organic frameworks (MOFs) applied in chemiresistors is principally limited by their poor conductivity and low catalytic activity. Herein, we report an intrinsically conductive two-dimensional (2D) MOF Co3(hexaiminotriphenylene)2 [Co3(HITP)2], for hydrogen sulfide (H2S) sensing at room temperature (RT). The proposed conductive Co3(HITP)2 sensor exhibits high sensitivity and good selectivity toward H2S under various relative humidity (RH) at RT. Meanwhile, different amounts of catalytic Pd nanoparticles (NPs) are embedded in conductive Co3(HITP)2 for further improving the gas sensing performances. The sensing results confirm that the 2 mol% Pd functionalized Co3(HITP)2 gas sensor presents the best sensing properties to H2S under different humidity at RT. We extended the catalytic metal NPs to Au and Pt, and Au or Pt loading conductive Co3(HITP)2 sensors also show remarkably enhanced H2S sensing performance including high response and low limit of detection (LOD). While, the pristine and noble metal NPs functionalized Co3(HITP)2 gas sensors are affected by humid atmosphere due to water vapor adsorption on Co3(HITP)2. Finally, the catalytic effect of noble metal NPs on conductive Co3(HITP)2 for H2S sensing is also discussed. The obtained results provide a key insight into the high-performance conductive Co3(HITP)2 based gas sensors work at RT for H2S detection.

The fabrication and investigations of a novel NO2 gas sensor based on a 1T and 2H mixed phase WS2 quantum dots (QDs) modified MOF-derived hollow In2O3 (WS2 QDs@In2O3) heterostructure were documented. The proposed gas sensor based on WS2 QDs@In2O3 hollow hexagonal prisms was simple, sensitive, cost-effective and worked at room temperature (25 ± 2 °C). The response value of 3 wt% WS2 QDs@In2O3 (W3In) towards 100 ppm NO2 could reach to 2034, which was an ultra-high value and almost 7.7 times higher than that of pure In2O3. Besides, our sensor showed excellent selectivity to NO2 and could detect concentration down to 100 ppb. The enhanced NO2 sensing performance was observed due to the synergistic effect between WS2 and In2O3. Furthermore, the compensation response values to NO2 based on the response to water vapor under different humidity of W3In were calculated and their fluctuations are within 7.8 % compared with the response under 25 % RH, which could provide a new strategy for accurately detecting NO2.

The design of a highly effective isopropanol gas sensor with high response and trace detection capability is extremely important for environmental surveillance and human health. Here, novel flower-like PtOx@ZnO/In2O3 hollow microspheres were prepared by a three-step approach. The hollow structure was composed of an In2O3 shell inside and layered ZnO/In2O3 nanosheets outside with PtOx nanoparticles (NPs) on the surface. Meanwhile, the gas sensing performances of the ZnO/In2O3 composite with different Zn/In ratios and PtOx@ZnO/In2O3 composites were evaluated and compared systematically. The measurement results indicated that the ratio of Zn/In affected the sensing performance and the ZnIn2 sensor presented a higher response, which was then modified with PtOx NPs to further enhance its sensing property. The Pt@ZnIn2 sensor exhibited outstanding isopropanol detection performance with ultrahigh response values under 22 and 95% relative humidity (RH). In addition, it also showed a rapid response/recovery speed, good linearity, and low theoretical limit of detection (LOD) regardless of being under a relatively dry or ultrahumid atmosphere. The enhancement of isopropanol sensing properties might be ascribed to the unique structure of PtOx@ZnO/In2O3, heterojunctions between the components, and catalytic effect of Pt NPs.

Our laboratory reported important three factors such as receptor function, transducer function and utility factor, for the material designs and their integration in 2003 and 2006, respectively. Based on the integration of such factors, the gas sensor using Pd-loaded SnO2 nanoclusters prepared by hydrothermal treatment could successfully detect toluene in ppb level. To enhance the sensor response more, we investigated the combination of such materials integration and pulse-heating of MEMS device, and found that such MEMS-type gas sensor has the lower detection limit for toluene gas to below 10 ppt. In addition, the Ultra-High-Sensitive detection for aliphatic compounds such as alcohol was also investigated.

Li7La3Zr2O12 (LLZ) has great potential as a solid electrolyte for co-fired all-solid-state Li-ion secondary batteries. However, to realise a solid-state battery using LLZ, the sintering temperature of LLZ should be reduced to one that can suppress the formation of a high-resistance reaction layer at the interface between LLZ and the electrode. In this study, we demonstrate an effective method for reducing the sintering temperature of Li6La3ZrTaO12 by combining partial Bi-substitution for Ta and precise control of the compositional deviation. The intentional tuning of the La deficiency in Li6La3ZrTa0.8Bi0.2O12 (LLZTB0.2) promoted the formation of a liquid phase based on Li2O–Bi2O3 at the grain boundary, resulting in its densification at 775 °C. Furthermore, we fabricated a co-fired all-solid-state half-cell based on an LLZTB0.2 electrolyte attached to a LiCoO2 + LLZTB0.2 composite electrode and a half-cell operated at 60 °C. From these results, it was found that the proposed concept is effective in reducing the sintering temperature of LLZ and is applicable for co-firing an all-solid-state battery.

Semiconducting nanomaterials with 3D network structures exhibit various fascinating properties such as electrical conduction, high permeability, and large surface areas, which are beneficial for adsorption, separation, and sensing applications. However, research on these materials is substantially restricted by the limited trans-scalability of their structural design and tunability of electrical conductivity. To overcome this challenge, a pyrolyzed cellulose nanofiber paper (CNP) semiconductor with a 3D network structure is proposed. Its nano-micro-macro trans-scale structural design is achieved by a combination of iodine-mediated morphology-retaining pyrolysis with spatially controlled drying of a cellulose nanofiber dispersion and paper-crafting techniques, such as microembossing, origami, and kirigami. The electrical conduction of this semiconductor is widely and systematically tuned, via the temperature-controlled progressive pyrolysis of CNP, from insulating (1012ω cm) to quasimetallic (10-2ω cm), which considerably exceeds that attained in other previously reported nanomaterials with 3D networks. The pyrolyzed CNP semiconductor provides not only the tailorable functionality for applications ranging from water-vapor-selective sensors to enzymatic biofuel cell electrodes but also the designability of macroscopic device configurations for stretchable and wearable applications. This study provides a pathway to realize structurally and functionally designable semiconducting nanomaterials and all-nanocellulose semiconducting technology for diverse electronics.

Development of highly sensitive toluene gas sensor is desirable but challenging for both indoor air quality monitoring and medical diagnosis. Herein, we proposed to design Au nanoparticles (NPs) decorated MOF-derived NiO/In2O3 hollow microspheres as efficient sensing materials for toluene detection. Benefiting from the structural merits and synergetic effects, the Au0.6Ni4In-based toluene sensor exhibited a high response, fast response and recovery speed, good linearity, low detection limitation (~5.1 ppb) with excellent selectivity and good stability in both relatively dry (11% RH) and ultra humid (95% RH) atmospheres. The improved toluene detection performance might be attributed to the synergistic effects of several points including the formation of p-n junction between NiO and In2O3, the sensitization effect of Au NPs, high affinity of NiO to water vapor as well as the loose structure. The obtained sensing performances unambiguously indicated that the Au0.6Ni4In-based sensor can quantitatively detect toluene at ppb-level in a complex environment.

To develop a highly sensitive carbon monoxide (CO) sensor with a wide range of humidity resistance, we focused on the Pd loading method on SnO2 nanoparticles and the thickness of the sensing layer. The Pd nanoparticles were loaded on the SnO2 surface using the surface immobilization method (SI-Pd/SnO2) and the colloidal protection method (CP-Pd/SnO2). The XPS analysis indicated that the Pd nanoparticles were a composite of PdO and Pd, regardless of the loading method. According to the evaluation of the electrical properties at 350 °C, the CO response in a humid atmosphere and the resistance toward humidity change using CP-Pd/SnO2 were higher than those using SI-Pd/SnO2, even though the Pd loading amount of SI-Pd/SnO2 was slightly larger than that of CP-Pd/SnO2. In addition, Pd/SnO2 prepared via the CP method with a thinner sensing layer showed a higher sensor response and greater stability to humidity changes at 300 °C, even though the humidity change influenced the CO response at 250 and 350 °C. Thus, the overall design of the surface Pd, including size, dispersity, and oxidation state, and the sensor fabrication, that is, the thickness of the sensing layer, offer a high-performance semiconductor-type CO gas sensor with a wide range of humidity resistance.

Metal-organic frameworks (MOF) with different Zn and Ni ratios (ZNOF-x) were synthesized by one-step solvothermal method without any surfactant. The ratio of Zn and Ni significantly affect the morphology of the ZNOF-x. Subsequently, MOF-derived ZnO-NiO (ZNO-x) was obtained after the calcination in air atmosphere. Gas sensing experimental was conducted on the as-fabricated ZNO-x sensors, and the measured results demonstrate that ZNO-x-based gas sensor presents lower acetone sensitivity but higher moisture-resistance performance with increasing the amount of Ni under ultra humid atmospheres. Especially, ZNO-5-based sensor exhibits a relative high sensitivity (1.31 to 1 ppm acetone in 95% RH atmosphere) and excellent water-vapour resistance performance (S95%/S11% > 0.8 at 175 °C), as well as good response and rapid response/recovery speed for the acetone sensing. Therefore, ZNO-5 is a promising material for acetone detecting in a high humid environment, which is a potential sensing material for the diagnosis of diabetes through exhaled gases analysis.

Clustered indium oxide/copper oxide (In2O3/CuO) nanospheres with different CuO amounts were successfully synthesized as sensing materials for the carbon monoxide (CO) detection. Component and morphological characterizations were performed by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), and X-ray photoelectron spectroscopy (XPS). Sensing performance for CO of the clustered In2O3 and In2O3/CuO nanospheres were investigated under different temperatures and humidity conditions. The results show that the sensors based on 2 mol % In2O3/CuO (InCu2) exhibit about threefold improvement in response to CO compared to that of In2O3 with quick response and recovery time, wide linearity, and low detection limit at 200 °C under 25% relative humidity (RH). Moreover, it shows tiny resistance and response declines despite the wide range of humidity variation from 25 to 95% RH. Meanwhile, the mechanism of enhanced gas-sensing performances and antihumidity properties of InCu2 were systematically investigated. We speculated that most of the water-driven species are predominantly adsorbed by CuO due to its high affinity to the hydroxyl group, which suppresses the interaction between moisture and In2O3. InCu2 is a new and promising material to sense CO in a highly sensitive and fast manner with negligible interference from ambient humidity.

Apatite-type lanthanum silicate (LSO) is a material with high oxide-ion conductivity in the low- and intermediateerature range (573-873 K) and is, therefore, a promising solid electrolyte for lowerature applications such as solid oxide fuel cells and oxygen sensors. Herein, the effect of B substitution at the Si site in a c-axis-oriented apatite-type lanthanum silicate (La_9.7Si_5.3B_0.7O_26.2, c-LSBO) polycrystal on oxide-ion conduction is investigated. A highly c-axis-oriented LSBO polycrystal is fabricated by a vapor-solid reaction in which a dense La₂SiO₅ disk is heated in B₂O₃ vapor at ≥1673 K. The oxide-ion conductivity of c-LSBO reaches 16 mS cm^-1 at 678 K with an activation energy of 0.4 eV. The obtained oxide-ion conductivity of c-LSBO is approximately 190 times higher than that of yttria-stabilized zirconia and 5.8 times higher than that of the polycrystalline c-axis-oriented nondoped lanthanum silicate. Based on ¹¹B nuclear magnetic resonance measurements, B is located at the SiO₄ site as BO₄, suggesting the formation of an oxygen vacancy at the O4 site located along the c-axis due to charge compensation. In addition, molecular dynamics simulations indicate that the oxide-ion diffusion coefficient of the B-doped LSO is higher than that of the nondoped LSO. The high oxide-ion conductivity of c-LSBO is likely attributable to the formation of an oxygen vacancy at the O4 site by B doping, which has a lower valency than Si. Therefore, c-LSBO is a promising candidate as a solid electrolyte in electrochemical devices operating at low and moderately high temperatures.

The ZnO tetrapods modified by TiO2 powder sensor is tested at 250–400 °C under different CO concentrations compared with pure ZnO tetrapods, ZnO nanoparticle, and ZnO powder sensors. With a good crystallinity and a high pore size, the ZnO tetrapods modified by TiO2 powder sensor shows the highest sensing response compared to other sensors, exhibiting a size-independent property for CO. Additionally, the response time of ZnO tetrapods modified by TiO2 powder sensor is reduced. The improvement of the sensing properties is attributed to microstructure, lattice, surface area, and conductance modification of TiO2 additive together with a high diffusion process deeply inside the sensing layer through the large pore size.

© 2017 WILEY-VCH Verlag GmbH & Co. KGaA, Weinhei/1. Colloidal semiconductor nanocrystals (NCs), called quantum dots (QDs), have been intensively studied because of their excellent photoluminescence (PL) quantum yields. However, commercial QDs such as CdSe and InP contain toxic or expensive rare elements, limiting their sustainable use. This study focuses on nontoxic, stable, and cheap tin oxides, and synthesized luminescent SnO2 NCs of ≈2 nm in size by a heating-up method. Tin precursors and diols in a high-boiling point solvent with oleylamine as the surfactant are heated at 240 °C. SnO2 NCs show defect-related photoluminescence at 400–460 nm by excitation at 370 nm, achieving a high quantum yield of more than 60%. The PL intensity is stable even when the NCs are stored in atmospheric air at room temperature for over 1 year. The defect-related emissions of the SnO2 NCs are studied using polyoxometalates (POMs) as the PL quencher. POMs efficiently quench the PL emissions by extracting excited electrons from the conduction band and shallow surface defects. The results reveal that PL emissions from SnO2 NCs are associated with radiative charge recombination via shallow defect levels on the surface and in the bulk, demonstrating the effectiveness of the PL quenching technique using POMs in studying the PL emission mechanism in QDs.

© 2016 Elsevier Ltd To investigate the material design of inks for high performance dielectric thin films constructed using BaTiO3 nanoparticles and polymer resin, the BaTiO3 mono-dispersed sol and the polymer solution were simply mixed and stirred to obtain the composite ink. The polymers chosen were cyanoethyl pullulan (CEP) and an epoxy. The dielectric constant of the BaTiO3/CEP composite thin film was higher than that of the BaTiO3 thin film and the BaTiO3/epoxy composite thin film because the dielectric constant of CEP is higher. Conversely, the resistance of the BaTiO3/epoxy composite thin films to frequency change was clearly greater than that of the BaTiO3/CEP composite thin films. Thus, the polymer component strongly affected the performance of dielectric constant. These results offer an important method for designing the dielectric composite ink for the development of thin film capacitors.

© 2016 American Chemical Society. In this study, we prepared thermally stable SnO2 nanocrystals (ca. 4 nm) in a mixture of SnCl4, tetraethylene glycol (TEG), and tetrabutylammonium hydroxide (TBAH) under reflux and obtained a highly sensitive semiconductor gas sensor. It has been determined both theoretically and experimentally that the synthesis of oxide semiconductor nanoparticles is an important factor in highly sensitive semiconductor gas sensors. However, as-synthesized nanocrystals generally grow large during calcination at high temperature, and this thermal crystal growth reduces the sensor response. Therefore, to refine the response of the semiconductor gas sensor, we synthesized thermally stable SnO2 nanocrystals by heating under reflux a SnCl4-TBAH-TEG mixture. The obtained SnO2 nanocrystals exhibited high thermal stability even when calcined at a temperature up to 600 °C. The gas-sensing films fabricated from the thermally stable SnO2 nanocrystals exhibited a high sensor response to hydrogen due to their small crystal size, and a change in their surface property as compared with conventional SnO2 nanocrystals synthesized via hydrothermal treatment.

Tungsten trioxide (WO3) is one of the important multifunctional materials used for photocatalytic, photoelectrochemical, battery, and gas sensor applications. Nanostructured WO3 holds great potential for enhancing the performance of these applications. Here, we report highly sensitive NO 2 sensors using WO3 nanolamellae and their sensitivity improvement by morphology control using SnO2 nanoparticles. WO 3 nanolamellae were synthesized by an acidification method starting from Na2WO4 and H2SO4 and subsequent calcination at 300 °C. The lamellae were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), and transmission electron microscopy (TEM), which clearly showed the formation of single-crystalline nanolamellae with a c-axis orientation. The stacking of each nanolamella to form larger lamellae that were 50-250 nm in lateral size and 15-25 nm in thickness was also revealed. From pore size distribution measurements, we found that introducing monodisperse SnO2 nanoparticles (ca. 4 nm) into WO3 lamella-based films improved their porosity, most likely because of effective insertion of nanoparticles into lamella stacks or in between assemblies of lamella stacks. In contrast, the crystallite size was not significantly changed, even by introducing SnO2. Because of the improvement in porosity, the composites of WO3 nanolamellae and SnO2 nanoparticles displayed enhanced sensitivity (sensor response) to NO2 at dilute concentrations of 20-1000 ppb in air, demonstrating the effectiveness of microstructure control of WO3 lamella-based films for highly sensitive NO2 detection. Electrical sensitization by SnO2 nanoparticles was also considered. © 2014 American Chemical Society.

High sensitivity and low limit of detection to volatile organic compounds (VOCs) gases are typical properties on the resistive-type semiconductor gas sensors using SnO2-based materials. In this few decades, semiconductor gas sensors were improved on the point of not only the sensitivity but also both compact and low power consumption by using the micro gas sensors equipped with the microheater and microelectrode using the MEMS (Micro Electronic Mechanical System) technique. Recently, we proposed the micro gas sensor driven in repeating mode of instantaneous heating and cooling (pulse-driving) [1,2]. According to the pulse-driving mode, VOCs gases can introduce into the sensing layer during cooling period, and it improves the utilize efficiency of the sensing layer. Thus, in this study, we aimed to improve the sensor response in low concentration of VOCs gases, SnO2 based gas sensor was driven under pulse-driving mode with monotonic and two-step heating.

To improve the sensitivity to volatile organic compounds (VOC) gases, a metal-oxide-based semiconductor gas sensor was operated under thermally modulated driving mode. We introduced the instantaneous switching of the heater for sensor driving, pulse-driven mode, using a miniaturized gas sensor constructed with micro-electrode and a micro-heater equipped by the MEMS technique. The switching mode of the sensor can absorb the gas molecules on the surface of particles, and detect a tiny quantity of gases by combustion of absorbed gases. In this study, we used the Pd-loaded SnO2 clustered particles, which is very sensitive to VOC gases, for the pulse-driven semiconductor gas sensors to decrease the lower detection limit of VOC gas concentration. According to the results, the Pd-SnO2 sensor achieved detecting the ppt level toluene detection under thermally modulated driven mode.

To detect the harmful gases in atmosphere using gas sensors is important for environment protection. Recently, the building gas sensors with high performance such as high gas sensitivity, rapid response and recovery, gas selectivity, and humidity resistance are strongly required. Resistive-type semiconductor gas sensors, especially SnO2-based gas sensors, are attracting the most attention because of their high potentiality. So far, we have reported that the introduction of three key factors, receptor function, transducer function and utility factor, to material design of sensors gives ultrahigh sensitivity in ppb level. However, the decrease in electric resistance by water vapor poisoning is most fundamental problem for practical use, because atmospheric environment includes water vapor and also the amount is different in each time and place. Recently, we tried to overcome such weak-point on SnO2-based gas sensors from viewpoint of materials design. For example, the decrease in electric resistance by water vapor poisoning can be improved by surface Sb substitution. Such materials design can raise the sensor performances and allow the practical use for environmental protection.

温度変調駆動を用いた粒子表面機能の増強による半導体ガスセンサの高性能化

末松　昂一、渡邉　賢、島ノ江　憲剛

CHEMICAL SENSORS 2021.9

　More details

Language：Japanese

Gas sensing performance of semiconductor gas sensor can be improved by not only the materials design but also the sensor driven mode using thermal modulation. Recently, we investigated the effect of instantaneous thermal modulation, which is switching the heater on/off (pulse-driven mode), using miniaturized gas sensor constructed with microheater and a pair of electrodes such as MEMS device. Pulse-driven mode, including the high-temperature preheating process, improved the particles surface functions such as adsorption function of gas molecules and oxygen dissociatively adsorption. Accordingly, pulse-driven mode enhanced up the sensor response and gas selectivity of the semiconductor gas sensors. Furthermore, we achieved the ppt level toluene detection by combining the sensor materials and driven designs.

金属酸化物半導体ガスセンサとMEMS（Micro-Electro-Mechanical-System）パルス駆動を融合することにより、これまで実現不可能とされているpptレベルの超高感度（Ultra-High-Sensitive）と超ガス選択性（Super-Selective）の両者を兼ね備えた新規なガスセンサを提案する。学術的には、これまで触媒反応の定常状態を信号としてきたガスセンサに、パルス駆動による選択的ガス吸着とその特異な反応過程という新規な速度論的解釈を導入し、さらにこれまでにない新たな情報応用の基礎を構築するものである。

パルス加熱駆動型半導体ガスセンサは、粒子表面の機能である吸着と燃焼反応促進を瞬時にスイッチでき、吸着ガス燃焼反応の非平衡過程を電気抵抗変化（応答波形）に変換できる。そこで本研究では、乳癌バイオマーカーとなるアルデヒド類を対象ガスとし、材料設計とセンサ駆動温度により、呼気を想定した妨害ガス共存下でバイオマーカーを選択的に吸着後、その燃焼反応に由来する応答波形の反応速度論的解析からバイオマーカーを特定する。さらにパルス加熱駆動の温度設計と応答波形の分離により複数種バイオマーカーの同時識別に挑む。

癌等に対する初期スクリーニングデバイスとして、小型・低消費電力かつ安価であり、微量ガスの高感度検出を得意とする、半導体ガスセンサが有用である。しかし、一般的に利用される定常加熱型半導体ガスセンサは、可燃性ガス全般に対して高感度であり、バイオマーカーガスの選択的検出が困難である。本研究では、露出結晶面を制御した異方性酸化物ナノ粒子を利用し、粒子表面のガス吸着特性を制御、半導体ガスセンサのガス選択性向上を図る。さらに近年申請者が提案している、パルス加熱駆動型半導体ガスセンサを利用することで、露出結晶面のガス吸着特性を最大限利用、微量バイオマーカーガスを選択的に検出可能な半導体ガスセンサを実現する。
