Abstract: In the present paper, we explore mainly the photochemical self-oxidate reaction of the benzyl alcohol (C6H5CH2OH) used as the reactant in the presence of the UV-illumination activated n-semi conductor catalysts TiO2Pt/TiO2) blended with and put forward the reaction mechanisms of ultraviolet ray illumination in term of the surface feature of Pt/TiO2 and "one-photon action model".
