CeO₂/TiO₂ photocatalyst was synthesized by sol-gel processing and dip-doping technique.Its physicochemical structure and properties were characterized.With pyridine n-octane system as the nitrogen source of simulative oil,the denitrification behavior of this photocatalyst under visible light was studied.The optimal photocatalysis reaction conditions were also explored.The doped cerium component in CeO₂ enhances the adsorption of catalyst in the visible light region.When the illumination time is 150 min under visible light,the amount of cerium doped is 8%,the dosage of the CeO₂/TiO₂ photocatalyst is 1.0 g/L,the denitrification percent of pyridine in the simulative oil reaches up to 76.45%.
