Country：Japan

In conventional semiconductor gas sensors, the combination of metal oxides and receptor functions has been considered crucial for sensor performance. However, there have been no established material design guidelines for achieving ultra-high sensitivity and selectivity, making the detection of gases at ppb or ppt levels previously deemed impossible.
In this study, we established three material design principles—receptor function, transducer function, and utilization efficiency—for gas detection interfaces, based on both theoretical and experimental approaches. Furthermore, by fully utilizing a wet-chemical synthesis method for sensor materials, we proposed a new high-performance gas sensor that integrates all three design principles. This sensor was also successfully applied to MEMS (Micro Electro Mechanical Systems) devices.
As a result of this research, these material design guidelines for semiconductor gas sensors have become widely recognized among gas sensor researchers worldwide. In my own work, I demonstrated the world’s highest sensitivity for toluene detection at the ppb level in 2014, and in 2018, developed a MEMS gas sensor with ppt-level sensitivity—far surpassing the olfactory capability of dogs.
These achievements are expected to contribute to the monitoring of extremely low-concentration environmental pollutants in residential settings, the breath-based diagnosis of diseases such as cancer and COVID-19, and the development of ultra-miniaturized gas analyzers.

Prof. Kengo Shimanoe has been engaged in the material design of oxide semiconductor gas sensors and has achieved outstanding research results in the field. Building upon the two previously proposed design principles—receptor function and transducer function—he has successively introduced a series of new ideas: the nanoscale effects of the receptor, identification of oxygen adsorption species and elucidation of the influence of water vapor, suppression of water vapor effects through surface modification, contact potential effects in n–n junctions, a new interpretation of depletion layer formation by oxygen adsorption, novel developments in particle size effects, and theoretical analysis and validation of gas response speed. Furthermore, he proposed the importance of a third design principle: the utility of the sensing layer, and presented a new design guideline that enables the detection of large gas molecules by controlling the hierarchical structure of the sensing film based on gas diffusion theory. Along with a model of a high-performance sensor integrating the above three design principles, he synthesized Pd-loaded SnO₂ clusters using wet chemical methods and successfully demonstrated toluene detection with the world's highest sensitivity (at the ppb level). His work has been widely cited in many scientific papers, and he has delivered numerous keynote and invited lectures at international conferences, as well as taken a leading role in organizing such events. These contributions have had a significant impact on science and technology.

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.

A new electrochemical oxygen separation pump was developed by using c-axis-oriented La9.66Si5.3B0.7O26.14 (c-LSBO), which has high oxide-ionic conductivity (>10−3 S cm−1) up to 300°C. Interfacial resistance between the electrode and c-LSBO was investigated to realize the full potential of LSBO as an oxygen separation material. The formation of a Sm-doped CeO2 (SDC) thin film (thickness: 300 nm) between the electrode and c-LSBO was effective for suppressing the interfacial resistance. Furthermore, a mixed conductive La0.6Sr0.4Co0.78Ni0.02Fe0.2O3−δ (LSCFN) was applied to the electrode for enhancing the oxygen reduction/evolution activity on the electrode. The LSCFN/SDC/c-LSBO symmetric cell showed an oxygen permeation flux of 3.5 mL cm−2 min−1 (1.0 A cm−2) at 600°C under an applied DC voltage of 1.5 V; this value was 67 times that of Pt/c-LSBO. This oxygen pump based on the LSCFN/SDC/c-LSBO symmetric cell would find promising application in oxygen separation at intermediate temperatures. Further reduction of the interfacial resistance and polarization resistance of the electrode may decrease the operating temperatures to below 400°C.

A surface functionalization route utilizing MoO3-loading was employed to activate ethanol adsorption and partial oxidation on the surfaces of SnO2 nanoparticles for use as highly sensitive ethanol sensors. STEM-EDS mappings verified that the majority of Mo ions were dispersed and doped into the lattice of the SnO2 nanoparticles as foreign receptors. According to catalytic combustion measurements of ethanol on the SnO2 surface, the MoO3-loading process decreased the complete oxidation but improved the yield of intermediates by accelerating dehydrogenation at low temperatures (50–250 ℃). We evaluated the sensing properties in the double-pulse-driven mode using a microheater constructed via a micro-electronic-mechanical-system technique. The sensor response Sp to ethanol of the MoO3-loaded SnO2 microsensor, 496, was dramatically higher than that of the neat-SnO2 microsensor, 3. The outstanding sensing performance was mainly attributed to the improved partial oxidation of ethanol and enhanced ethanol adsorption capacity due to the introduction of Mo ions. The results provide promising insights into the material design for highly sensitive ethanol detection by controlling gas adsorption and combustion.

Thickly and densely sintered electrodes (TDSE) consisting of active materials can achieve highly capacitive Li-ion batteries and are one of the ideal electrode structures applicable for co-sintered-type solid-state batteries based on oxide-based solid electrolytes. This study focused on Li3xLa2/3−xTiO3 (LLTO) as the TDSE for the anode. LLTO exhibits high Li-ion conductivity and a high capacity of 225 mAh g−1 with an operation potential below 1 V (vs. Li+/Li). However, the electronic conductivity of LLTO is low (less than 10−8 S cm−1), and the improved electronic conductivity seems necessary. In this paper, we investigated the electrochemical properties of LLTO sintered electrodes and improved the electronic conductivity of LLTO by Mn substitution for the Ti site. LLTO shows a huge overpotential during initial Li insertion due to low electronic conductivity of 1.1 × 10−9 S cm−1, resulting in extremely low capacity. On the other hand, Mn substitution enhances the electronic conductivity, resulting in improved first-cycle charging properties.

Increasing the capacity of Li-ion batteries is one of the critical issues that must be addressed. A thick and dense electrode using an active material sintered disk is expected to have a high capacity because the volume of the active material is 100% in the cathode. This study focused on LiCoO2, the most well-known active material for the cathode, to improve the properties of the sintered cathode. We investigated the impact of excess Li on various properties. We found that the degree of c-axis orientation in the sintered disk decreased as excess Li increased. In addition, results of 7Li-MAS-NMR suggest the presence of defects resulting from excess Li when the Li excess reached 5.1% or more. The discharge capacity of the LiCoO2 sintered cathode increased as the amount of excess Li increased, and a maximum discharge capacity of 11.2 mA h cm−2 was obtained when the Li excess amount was 7.3%. This result was attributed to the significant improvement in the Li-ion conductivity of LiCoO2 by both the decrease in the degree of c-axis orientation and the introduction of defects due to excess Li. Notably, introducing defects derived from excess Li enhances the Li-ion conductivity. Thus, tuning the amount of excess Li for the LiCoO2 sintered cathode was crucial in enhancing its electrochemical performance as an electrode.

Bi2O3 particles are introduced as foreign additives onto SnO2 nanoparticles (NPs) surfaces for the efficient detection of oxygenated volatile organic compounds (VOCs). Bi2O3-loaded SnO2 materials are prepared via the impregnation method followed by calcination treatment. The abundant Bi2O3/SnO2 interfaces are constructed by the uniform dispersion of Bi2O3 particles on the SnO2 surface. The results of oxygen temperature-programmed desorption suggest that Bi2O3-loaded SnO2 samples display improved surface oxygen ions than neat-SnO2 NPs. As a result, the gas sensor based on 1 mol% Bi2O3-loaded SnO2 (1Bi-L-SnO2) composites shows significantly higher sensitivity and a faster response speed toward various oxygenated VOCs compared with SnO2, especially at 200 °C and 250 °C. The results of catalytic combustion and temperature-programmed reaction measurements reveal the dominant role of adsorption and partial oxidation during ethanol combustion on SnO2 and 1Bi-L-SnO2 surfaces. In this case, the improvement in the sensing performance of the 1Bi-L-SnO2 sensor can be associated with the increase in surface oxygen ions at Bi2O3/SnO2 interfaces. The results confirm the significant role of surface functionalization for sensing materials. The obtained outstanding sensing performance provides the potential application for the simultaneous detection of total oxygenated VOCs in practice.

Co-sintering a cathode material and garnet electrolyte to develop a bulk-type solid-state Li metal battery with wide electrochemical windows

Co-sintering a cathode material and the Li7La3Zr2O12 (LLZ) electrolyte can assist in fabricating bulk-type all-solid-state batteries (ASSBs). However, owing to the use of low temperatures to prevent reactions between the different materials, this process can result in low relative densities and ionic conductivities. To overcome this trade-off between sintering temperature and electrochemical performance, a highly sinterable Ca-Sb-doped LLZ electrolyte integrated with the sintering aids Li7SbO6 and Li3BO3 was developed in this study. A composite powder of Li6.5(La2.925Ca0.075)(Zr1.425Sb0.575)O12 (denoted as LLZ-CaSb) and xLi7SbO6 (x = 0-0.14), whose composition differed from that of stoichiometric LLZ-CaSb, was prepared, with Li3BO3 added prior to sintering. The disk incorporated with the sintering aid 0.08Li7SbO6 (x = 0.08) and then sintered at 750 °C exhibited a relative density and ionic conductivity of 87% and 3.1 × 10−4 S cm−1, respectively, indicating its superior sintering properties. The formation of a low-melting-point liquid phase, generated by the mutual reaction between Li-Sb-O- and Li-B-O-type oxides, promoted sintering. The developed electrolyte exhibited a wide potential window (5 V vs. Li/Li+). The ASSB assembled using the co-sintered LiCoO2/electrolyte system and Li metal anode maintained 98.6% of the initial discharge capacity (120.7 mA h g−1) after 60 cycles at 25 °C and 0.1C and performed adequately over a wide temperature range (−25 to 120 °C). The method reported herein has potential for achieving cost-effective large-scale ASSB production.

Li7La3Zr2O12 (LLZ) is a promising candidate electrolyte for co-fired all-solid-state Li-ion batteries. However, its application is hindered by the reaction between LLZ and electrode materials during high-temperature sintering. To reduce the sintering temperature, herein Li-Bi-O oxide is added as a low-melting-point material into Ca-Bi co-doped LLZ (LLZ-CaBi). Nanocomposites of Li6.5(La2.92−xCa0.08)(Zr1.42Bi0.58)O12 and Li-Bi-O are fabricated. Here, Li-Bi-O is formed in the particles by intentional composition tuning using a lower amount of La than the stoichiometric composition. Direct observation of the nanocomposite reveals Li-Ca-Bi-O, Ca-Bi-O, and Li2CO3 in mother LLZ-CaBi particles. Some properties improve as x increases, and after sintering at 750 °C the highest relative density of 94% and ionic conductivity of 1.2 × 10−3 S cm−1 are achieved at x = 0.13. Li, Ca, and Bi are dissolved in the liquid phase and re-precipitated to promote further densification. The dependence of ionic conductivity on x is well explained by the relative density and alleviation of bottlenecks in the Li-ion diffusion path. Moreover, the developed LLZ-CaBi could be co-fired with LiCoO2, and the co-fired half-cell successfully operates as an all-solid-state battery at room temperature. Thus, the composite of LLZ-CaBi with Li-Bi-O can be applied as a catholyte in solid-state batteries.

Gas sensing investigation indicates that the sensor based on 6 at% Sn2+ doped NiO nanofibers with an elevated baseline resistance exhibits the highest gas response and excellent recovery characteristic to TEA at 200 °C. The sensor shows a low detection limit at ppb level and good long-term stability within three months. In addition, the sensor only has a small variation on baseline resistance, gas response and response/recovery speed under different relative humidity. The promising gas sensing performance can be mainly attributed to the increase of the oxygen vacancies defects caused by the difference of Sn2+ and Ni2+, resistance changes and the hollow structure of as-prepared nanofibers.

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.

In this work, Sn4+ doped NiO nanofibers are modified by different contents of Rh2O3 through a facile electrospinning method to improve the gas sensing properties, especially the humidity tolerance, response value and detection limit. The morphological characterization indicates that the hollow nanostructures are still maintained after loading Rh2O3. Gas sensing investigation demonstrates that 6 at% Sn4+ doped NiO nanofibers modified with 6 at% Rh2O3 exhibit the highest response to triethylamine (28.3–20 ppm) with low detection limit (50 ppb) at a relatively low working temperature (165 °C), which are obviously superior to those (16.6–100 ppm, 500 ppb and 180 °C) of 6 at% Sn4+ doped NiO nanofibers without Rh2O3 modification. The response value to 20 ppm triethylamine is only changed about 35.7% as the relative humidity increases from 35% to 95%. The humidity tolerance of the optimal sensor is also improved after Rh2O3 modification including the baseline resistance and gas response changes. Furthermore, the baseline resistances of the optimal gas sensors don't become higher after Rh2O3 modification. These phenomena can be mainly attributed to the improved catalytic effect and increased surface defects caused by Rh2O3 modification.

Li7La3Zr2O12 (LLZ) is one of the most promising Li-ion solid electrolytes for all-solid-state Li-ion batteries. To achieve low interfacial resistance between LLZ and the active material, low-temperature sintering is required. Toward this, we co-doped Ca and Bi into LLZ and used Li3BO3 as an additive to examine these species as sintering aids. We successfully demonstrated that Li6.5La2.9Ca0.1Zr1.4Bi0.6O12 containing Li3BO3 can be sintered even at 750 °C with a relative density of 89% and conductivity of 3 × 10−4 S cm−1 at 25 °C. Thermomechanical and microstructural analyses revealed that the starting temperature of the viscous flow, which was initiated by the formation of a liquid Li3BO3 phase, was reduced owing to the reaction between Ca2+ and Li3BO3. Additionally, the Li-Ca-Bi-O liquid phase formed between the LLZ particles during sintering improved the sinterability, which consequently promoted the necking between particles and lowered the grain boundary resistance. Additionally, we demonstrated that the developed LLZ was applicable as an electrolyte for all-solid-state lithium-ion batteries with high cycling stability. Thus, Li6.5La2.9Ca0.1Zr1.4Bi0.6O12 containing Li3BO3 is a promising candidate as an electrolyte for the cathode layer of all-solid-state lithium-ion batteries.

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.

Exploring sensing materials with superior catalytic properties is of paramount importance for acetone detection. In this work, NiO/NiFe2O4 nanocubes derived from Ni/Fe bimetal metal-organic frameworks (MOFs) precursors are synthesized by one-step impregnation method and subsequent annealing process. The microstructure and morphology of the synthesized samples are investigated by a series of characterization. The results indicate that uniform and porous NiO/NiFe2O4 nanocubes are formed. The gas sensing properties of NiO/NiFe2O4 composites are systematically evaluated. Benefitting from the synergistic effect of abundant sites, p-p junction and high surface area, the optimal sensors based on NiO/NiFe2O4 (Ni/Fe=1.5 at) exhibit the best sensing performance. The sensors show the highest response (19.9–100 pm acetone), short response/recovery times (2.4 s/19.6 s), low detection limit (200 ppb) and a good humidity tolerance ((S35% RH-S95% RH)/S35% RH= 0.095) to acetone at 200 °C. The results offer us a promising alternative to develop an ideal platform for acetone detection.

The tin–metal mixed hydroxides CaSn(OH)6, MnSn(OH)6, CoSn(OH)6, and ZnSn(OH)6, with cubic morphologies, were prepared using a coprecipitation method; they were subsequently transformed into the corresponding tin–metal mixed oxides by calcination at 600–900 °C. The crystalline structures and the morphologies of the various samples at each calcination step (just prepared, dried at 110 °C, and calcined at 600 and 900 °C) were systematically evaluated by X-ray diffractometry, scanning electron microscopy, transmission electron microscopy, and X-ray absorption fine structure analyses. The cubic shapes of the CaSn(OH)6 and ZnSn(OH)6 nanoparticles were maintained after calcination of them at 600 and 900 °C, while those of MnSn(OH)6 and CoSn(OH)6 ones were not maintained after calcination of them.

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.

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.

Amplifying the receptor function on Ba0.9La0.1FeO3-SnO2 composite particle surface for high sensitivity toward ethanol gas sensing

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.

Two Types of Moisture Effects on the Receptor Function of Neat Tin Oxide Gas Sensor to Oxygen Reviewed

Noboru Yamazoe, Koichi Suematsu, Kengo Shimanoe

Sensors and Actuators B: Chemical 2013.1

　More details

Language：English

Influences of moisture on the response of a neat tin oxide gas sensor to oxygen at 623 K were investigated. Two types of moisture effects were easily recognized, that is, moisture acted as a inhibitor to the oxygen adsorption in form of O− (type I sites) and O2− (type II sites) by being adsorbed competitively (short term effect), whereas the moisture admitted at elevated temperature acted as a promoter to increase the population of type II sites or the adsorptive strength of type I sites (long term effect). A tremendous increase of the type II site population as well as the existence of threshold pressure for oxygen adsorptionon the same sites suggests the formation of a sort of surface hydrate, dehydration of which seems to leave type II sites behind. The response to oxygen could be reproduced satisfactorily by using adsorption constants of oxygen and water, threshold pressure of oxygen and semiconductor properties of tin oxide.
