abstract = "The photocatalytic activity of carbon-doped TiO2 prepared by the sol-gel method was studied. The decomposition of acetaldehyde under visible light illumination showed that modified TiO2 catalyst had activity under visible irradiation of > 420 nm), eight times higher than that of commercial P25 TiO2. Elemental carbon was doped both on the surface and inside the bulk of TiO2. The elemental carbon acted as a photosensitizer. Under visible light irradiation, the excited photosensitizer injected the electron into the conduction band of TiO2 and then the electron was transferred to adsorbed O2, producing superoxide radical anion O2•- that participated in the oxidation of acetaldehyde. This is an abstract of a paper presented at the AIChE Annual Meeting (Salt Lake, UT 11/4-9/2007).",
