Kondo教授の研究室では、メソ多孔性酸化物の結晶化と構造制御を核とした機能性酸化物材料の創出を進めています。特に、高温処理による構造崩壊を防ぐための強化技術を用い、結晶性でありながら高い秩序を持つメソ多孔構造を実現しています。この技術を応用して、水の全分解を促進する高効率な光触媒の開発も行われており、環境・エネルギー分野への応用が目指されています。

Crystallization of an amorphous inorganic network of mesoporous metal oxides is achieved while maintaining the original ordered mesoporous structure. The methodology utilizes reinforcement (carbon or silica) to strengthen the periodic structure so that the original ordered mesoporous structure is preserved during thermal treatment for crystallization. The reinforcement is removed after crystallization to provide crystalline mesoporous metal oxide with the original ordered structure. Enhancement
The adsorption and reaction of H2, CO, CO2, OH(a)+ CO(g) and CO2(a)+ H2(g) have been studied in detail by infrared spectroscopy. Hydrogen is dissociatively adsorbed to form the OH and the Zr—H species and CO is weakly adsorbed as the molecular form. The infrared spectrum of adsorbed species of CO2 over ZrO2 shows three main bands at ca. 1550, 1310 and 1060 cm–1 which can be assigned to the bidentate carbonate species. The reaction of OH(a)+ CO(g) at 373 K gave rise to formate and bidentate carbo
