Enomoto, Naoya, Nishimura, Yusaku, Inada, Miki, Unconscious factors affecting physical characteristics of sol–gel-derived monodispersed silica spheres, Journal of Sol-Gel Science and Technology, 10.1007/s10971-022-05917-7, 104, 3, 512-518, 2022.12, Syntheses of monodisperse silica spheres (MSS) and monodisperse mesoporous silica spheres (MMSS) were studied focusing on the age of starting solutions, the solvent partitioning, and the surfactant dissolution as unconscious process factors. Aging of clear and transparent starting solutions decreased nucleation and increased the size of MSS, while the aging effect was opposite in the case of MMSS. Alcohols were used as co-solvent for alkoxides and water to dilute them. Partitioning ratio of alcohols was also a factor that changes the sphere size. Even when a surfactant is soluble in water and alcohol to readily form a transparent starting solution, the clusters consisting of solute and solvent molecules or their molecular level dissolution states may vary during aging, and thus could be a factor affecting the nucleation of nanoparticles. Aging of a methanolic solution of tetramethylorthosilicate (TMOS) containing a surfactant (C16TAC; cetyltrimethylammonium chloride) resulted in unfavorable formation of irregular (non-spherical) particles probably due to the interaction between TMOS and a moisture in the surfactant during aging..

22. Naoyoshi Nunotani, Muhammad Radzi Iqbal Bin Misran, Miki Inada, Tomoki Uchiyama, Yoshiharu Uchimoto, Nobuhito Imanaka, Structural environment of chloride ion-conducting solids based on lanthanum oxychloride, Journal of the American Ceramic Society, 10.1111/jace.16727, 103, 1, 297-303, 2020.01, The effect of the structural environment on the Cl− ion conductivity was demonstrated in LaOCl-based solid electrolytes. By replacing the La3+ site with lower-valent Mg2+ or Ca2+ ions, the conductivity was enhanced owing to the formation of a Cl− ion vacancy. Despite the same dopant content, the conductivity of La0.8Ca0.2OCl0.8 was considerably greater than La0.8Mg0.2OCl0.8. This enhancement of the conductivity was influenced by the high ionicity of the Cl− ions, which facilitated the weakening of the La-Cl bond cleavage to conduct inside the lattice. The elongation of the La-La distance, associated with the Cl− ion conduction, could also cause an increase of the conductivity..
23. František Mikšík, Takahiko Miyazaki, Miki Inada, Detailed investigation on properties of novel commercial mesoporous silica materials, Microporous and Mesoporous Materials, 10.1016/j.micromeso.2019.109644, 289, 2019.11, A detailed investigation on the main characteristics was conducted on a novel and unique group of industrially produced mesoporous silica material. Six materials from a TMPS group were selected in the respect to their pore size ranging from 1.8 nm up to 4.2 nm. Four of the selected samples were also made with silica doping making them potentially attractive for water adsorption applications with the advantage of the pore-tuning possibilities for specific use. The surface area, pore volume and pore size distribution of these materials were established by standard nitrogen adsorption at T = 77.4 K showing typical values of mesoporous silica materials such as high surface area in the range from 600 to 750 m2g−1 and pore volumes reaching 0.38 cm3g−1 in the case of the smallest TMPS-1.5A and 0.98 cm3g−1 in the case of the largest TMPS-4R. The wall thickness was found out regular around 1.5 ~ 2 nm with lower values attributed to bigger pore sized samples promising good structural integrity. Specific heat showed regular values through all the samples at ~ 0.85 J g−1K−1. Additional information on the structural characteristics and the effect on the amount of silanol group presence and the difference on regular and aluminium-doped samples were studied by means of 29Si DD/MAS NMR. Additionally, elemental analysis by EDS was conducted as well. All the characteristics of the TMPS materials were compared to the standard mesoporous silica materials SBA-15 and MCM-41..
24. Angga Hermawan, Yusuke Asakura, Miki Inada, Shu Yin, One-step synthesis of micro-/mesoporous SnO2 spheres by solvothermal method for toluene gas sensor, Ceramics International, 10.1016/j.ceramint.2019.05.043, 45, 12, 15435-15444, 2019.08, A facile solvothermal synthesis in an ethanol/acetic acid mixture for the fabrication of SnO2 with a controllable hierarchical spherical size and micro-/mesoporosity is presented. SEM, TEM and N2 adsorption/desorption investigation unveiled that the obtained SnO2 spheres exhibited a particle size in the range of 0.6–1.6 μm and a pore size of about 1.4–1.9 nm depending on the volume ratio of acetic acid to ethanol in the reaction mixture, and the spheres were constructed by nanoscale particles. Due to its micro-/mesoporous structure, the SnO2 spheres exhibited large specific surface areas over 100 m2/g. When 10 vol. % of acetic acid at 200 °C for 20 h was used for the reaction, the obtained SnO2 possessed a higher specific surface area of 145 m2/g (SnO2_10). The gas sensing property of SnO2_10 without an additional noble metal co-catalyst exhibited a large toluene sensing response (Ra/Rg) of 20.2 at 400 °C, which was about 6 times higher and acceptable selectivity compared to those of other samples. The study found that the sensing performance in the SnO2 hierarchical spheres was influenced by several factors e.g. particle morphology, pore size and specific surface area rather than only a single parameter. Therefore, a precise control of those influencing parameters may lead to the optimum sensing property. These findings are important for the further development of the micro-/mesoporous metal-based oxide as an alternative successor for toluene gas sensor material..

He Wang, George Hasegawa, Yuto Akiyama, Takahisa Yamamoto, Atsushi Inoishi, Hirofumi Akamatsu, Miki Inada, Tatsumi Ishihara, Katsuro Hayashi, A highly conductive Na3V2(PO4)3ceramic sheet prepared by tape-casting method, Electrochimica Acta, 10.1016/j.electacta.2019.03.057, 305, 197-203, 2019.05, Ceramic sheets of Na3V2(PO4)3(NVP) with NASICON-related structure have been prepared by tape-casting method. The addition of 60Na2O-10Nb2O5-30P2O5 glass to NVP is demonstrated to enhance markedly the density of the sintered NVP sheet and its electrical conductivity. The best densified NVP sheet with a thickness of a few tens of μm is obtained by sintering tape-casted NVP added with 5 wt% glass at 920 °C, which exhibits a total conductivity of 2.9 × 10−5 S cm−1 at room temperature. A Pt | NVP sheet | Pt cell works as a tiny solid-state battery with a cell potential of 1.7 V, in which NVP acts as both cathode and anode active materials via redox reactions of V4+/V3+ and V3+/V2+ as well as a Na+ ion conducting electrolyte between the two electrode layers..
26. George Hasegawa, Kei Kawahara, Kazunari Shima, Miki Inada, Naoya Enomoto, Katsuro Hayashi, Characterization of an AX Compound Derived from Ti2SC MAX Phase, European Journal of Inorganic Chemistry, 10.1002/ejic.201900311, 2019, 17, 2312-2317, 2019.05, Extraction of M elements from MAX phases results in “AX” compounds in contrast to the well-defined two-dimensional (2D) materials known as MXene, which are prepared by the selective etching of A elements. Despite the extensive studies on MXene from both experimental and computational aspects, the nature of the AX compounds still remains elusive, because the electrochemical etching of M atoms from MAX significantly spoils the crystal structure, predominantly resulting in amorphous AX products. Here, we demonstrate the characterization of an S/C complex prepared by the electrochemical etching of Ti2SC. The spark plasma sintering (SPS) technique affords a well-sintered Ti2SC disk with high purity, which can be directly utilized as a binder-free Ti2SC electrode. It is found that the electrochemically extracted Ti elements in NH4F electrolyte are partially crystallized into the monoclinic titanium oxynitride, TiO0.34N0.74. The formed amorphous S/C compound is classified into three components: acetone-soluble volatiles including elemental sulfur, acetone-insoluble volatiles, and non-volatile species carbonizable into S-doped carbon..
27. Yasuhiro Uchida, George Hasegawa, Kazunari Shima, Miki Inada, Naoya Enomoto, Hirofumi Akamatsu, Katsuro Hayashi, Insights into Sodium Ion Transfer at the Na/NASICON Interface Improved by Uniaxial Compression, ACS Applied Energy Materials, 10.1021/acsaem.9b00250, 2, 4, 2913-2920, 2019.04, A robust ceramic solid electrolyte with high ionic conductivity is a key component for all-solid-state batteries (ASSBs). In terms of the demand for high-energy-density storage, researchers have been tackling various challenges to use metal anodes, where a fundamental understanding on the metal/solid electrolyte interface is of particular importance. The Na+ superionic conductor, so-called NASICON, has high potential for application to ASSBs with a Na anode due to its high Na+ ion conductivity at room temperature, which has, however, faced a daunting issue of the significantly large interfacial resistance between Na and NASICON. In this work, we have successfully reduced the interfacial resistance as low as 14 ω cm2 at room temperature by a simple mechanical compression of a Na/NASICON assembly. We also demonstrate a fundamental study of the Na/NASICON interface in comparison with the Na/β′′-alumina counterpart by means of the electrochemical impedance technique, which elucidates a stark difference between the activation energies for interfacial charge transfer: ∼0.6 eV for Na/NASICON and ∼0.3 eV for Na/β′′-alumina. This result suggests the formation of a Na+-conductive interphase layer in pressing Na metal on the NASICON surface at room temperature..
28. Shingo Hirata, Miki Inada, Naoya Enomoto, Katsuro Hayashi, Junichi Hojo, Kinetic approach for the adsorption-photodecomposition properties of mesoporous silica-titania, Journal of the Ceramic Society of Japan, 10.2109/jcersj2.19003, 127, 4, 242-248, 2019.04, We have fabricated mesoporous silica-titania by a solgel method and evaluated the photocatalytic activity using acetaldehyde. The synthesized mesoporous silica-titania was effective for the removal of acetaldehyde from gas phase by adsorption and photodecomposition. In this study, the kinetic approach was carried out in order to clarify the adsorption-photodecomposition property of mesoporous silica-titania. The adsorption, direct photodecomposition and concerted adsorption-photodecomposition can be separately described in our simulation curves, which indicates that the adsorbability strongly affects the removal of acetaldehyde in the early stage and the photodecomposition after the strong adsorption of acetaldehyde on mesoporous silica-titania is important for the complete removal of acetaldehyde from gas phase..
29. Joji Hasegawa, Moeko Tanaka, Junie Jhon M. Vequizo, Akira Yamakata, Hajime Hojo, Makoto Kobayashi, Masato Kakihana, Miki Inada, Hirofumi Akamatsu, Katsuro Hayashi, Sodium titanium oxide bronze nanoparticles synthesized via concurrent reduction and Na+-doping into TiO2(B), Nanoscale, 10.1039/c8nr08372j, 11, 3, 1442-1450, 2019.01, A mixed valence compound, sodium titanium oxide bronze (NaxTiO2-B), combines intriguing properties of high electric conductivity and good chemical stability together with a unique one-dimensional tunnel crystal structure available for cation storage. However, this compound has not been studied for a long period because of the strongly reductive condition at high temperature required for its preparation, which limits the morphological control such as the preparation of nanocrystals. For the first time in this paper, the topotactic synthesis of nano-sized NaxTiO2-B with high specific surface area (>130 m2g-1) from TiO2(B) nanoparticles has been demonstrated. The reaction of metastable TiO2(B) with NaBH4 allows carrier electrons to be doped simultaneously with incorporation of Na+ ions into the interstitial sites of the host Ti-O lattice at relatively low temperature. An electrochemical investigation of Li+- and Na+-ion storage behaviors suggests that the incorporated Na+ ions are mainly placed in the 6-fold coordination sites of bronze. In addition, optical measurements including time-resolved transient spectroscopy revealed that the doped electrons in the NaxTiO2-B nanoparticles are predominantly in the Ti3+ state and behave as a small polaron. The pelletized NaxTiO2-B nanoparticles shows a good electronic conductivity of 1.4 × 10-2 S cm-1 at 30 °C with an activation energy of 0.17 eV, which is attributable to the thermal barrier for the polaron hopping..
30. Shunta Nishioka, Kei Ichi Yanagisawa, Daling Lu, Junie Jhon M. Vequizo, Akira Yamakata, Koji Kimoto, Miki Inada, Kazuhiko Maeda, Enhanced water splitting through two-step photoexcitation by sunlight using tantalum/nitrogen-codoped rutile titania as a water oxidation photocatalyst, Sustainable Energy and Fuels, 10.1039/c9se00289h, 3, 9, 2337-2346, 2019.01, Rutile TiO2 codoped with tantalum and nitrogen (TiO2:Ta,N) was assessed as a water oxidation photocatalyst for Z-scheme water splitting driven by visible light. This material was prepared by thermal ammonolysis of TiO2:Ta with dry NH3 at 773 K, while samples of the oxide precursor were synthesized using a microwave-assisted solvothermal technique, applying various conditions. The photocatalytic activity of the TiO2:Ta,N during water oxidation to O2 from an aqueous FeCl3 solution was found to be greatly affected by the synthesis parameters. The rate of O2 evolution was increased upon increasing the level of Ta doping in conjunction with a highly-crystalized TiO2:Ta precursor resulting from applying a higher temperature during synthesis of the oxide. IrO2 loading of the TiO2:Ta,N photocatalyst also improved the O2 evolution activity. The optimized IrO2/TiO2:Ta,N photocatalyst was applied to a Z-scheme water splitting system in combination with Ru/SrTiO3:Rh and in the presence of redox mediators (Fe3+/2+ or [Co(bpy)3]3+/2+). Under AM1.5G simulated sunlight, this system exhibited a maximum solar-to-hydrogen energy conversion efficiency of 0.039%, which was nearly twice as high as the previously reported system with the use of RuO2/TiO2:Ta,N (0.021%)..

The single-phase C3AH6 is separated into Ca(OH)2 (to CaO afterward) and C12A7 by means of the spinodal decomposition on heating, giving rise to the cocontinuous mesoporous structure in a cubic mesocrystal after removing the byproducts. The mesopore size can be tuned simply by varying calcination temperature and/or duration time. The catalytic study reveals that the mesoporous C12A7 microcubes can work out as a good support for Ru catalyst even without reduction..
