Research Content & Progress:
This study is focused on design of photocatalysts, improvement in photocatalytic properties and opti-mization of photocatalytic reaction system. We study the effects of d and s valence electrons on band structures of photocatalysts, tune the position of valence band and conductor band by solid solution, and extend the absorption of photocatalysts to visible light by doping. We also study the preparation of photocatalysts with mesoporous structure or special morphology, the photocatalytic water splitting of eosin sensitized TS-1 molecular sieve, and the effects of base or acid sites on photocatalytic properties. We have prepared the magnetically separated composite photocatalysts, and foamed Ni loaded TiO2/ SiO2, TiO2/Al2O3. Inert interface was used to increase the specific surface area of the photocatalysts by 30 times, thus improving the number of reaction sites. Photocatalysts with photoluminescence was studied to obtain photocatalytic properties without exterior irradiation. We also designed an equipment of photocatalytic water splitting into hydrogen using solar energy, and a system of hydrogen production combined with its application.
