Abstract: The effects of different proportions of CO Ag supported on ZnO on the selective catalytic oxidation of styrene to benzaldehyde were investigated with H2O2 as oxidant. The catalysts were prepared by sol-gel method and characterized by XRD, FT-IR, TG-DTG, BET and SEM EDX. The effects of solvent, temperature, substrate oxidant molar ratio, reaction time and doping rate on the performance of the catalyst were investigated. Zn1 − x, − yagxcoyo catalyst has good activity and high selectivity for benzaldehyde (95 ), and the yield of acetophenone is only 5 .
