Outline of Final Research Achievements

Inorganic porous materials with precise control of hierarchical pore structure, especially porous siliceous materials with hierarchical macroporous and mesoporous architectures, were used as supports in the design of catalysts and photocatalysts for application to environmental purification. The advantageous porous structure enables the loading of small and highly dispersed metal nanoparticles (i.e., Pt, Pd, and Ni) with a narrow size distribution, which realizes the significant enhancement of catalytic performances in various reactions. Specific characteristics were also confirmed in the adsorption profiles of organic molecules in water and air. After loading of TiO2, enhanced photocatalytic properties were observed in the degradation of relatively large organic molecules.
