TiO2 based photocatalysis has been widely investigated and has vital applications in energy and environmental remediation processes. In this connection research is being conducted in the zone of supported TiO2 based photocatalysts for development of visible light induced photocatalytic material. A series of materials were synthesized including zeolite based composite photocatalyst, N-doped mesopourous titania and investigated for dye degradation followed by hydrogen generation. Current research trend is towards supported photocatalyst therefore silica gel supported TiO2 photocatalyst was designed and developed also compared with alumina based photocatalyst. From the experimental data it was found that Silica based system has edge over the other synthesized photocatalysts with effective dye degradation of about 9.61 mg of MO reduced per g of TiO2 (0.508 mg of MO reduced per g of TiO2 for Degussa P-25). MO photoreduction is 19 times higher as compared to benchmark material Degussa P-25. Results well illustrate the formation of high dispersed metal oxide on silica framework.
