In nano TiO2 photocatalytic oxidation system, adding inorganic oxidizing species can efficiently trap photogenerated electrons and increase concentrations of hydroxyl radicals in the solution and enhance the photocatalytic oxidation rate of nano TiO2 to different organic matter. In this study, correlation of the production of hydroxyl radicals and the photoinduced electron tranfer of nano-TiO2 by inorganic oxidizing species (K2S2O8) was verified by means of the free radicals measured by spin trapping-ESR methods in which DMPO was selected as the spin-trap. The photocatalytic oxidation mechanism of glycine was studied.
