抄録

Two different Ti-containing porous silica thin films having a hexagonal and cubic pore structure were synthesized and used as photocatalysts for the reduction of CO 2 with H 2O at 323 K. UV irradiation of the Ti-containing porous silica thin films in the presence of CO 2 and H 2O led to the formation of CH 4 and CH 3OH with a high quantum yield of 0.28%. These porous silica thin film photocatalysts having a hexagonal pore structure exhibited higher reactivity than the Ti-MCM-41 powder photocatalysts with the same pore structure.
