Abstract：The selective oxidation of benzyl alcohols was achieved by using g-C3N4-supported platinum as the catalyst under light irradiation,which provides an effective method for synthesizing arylformaldehydes.The reactions were performed under conditions of light irradiation and Pt/g-C3N4 catalyst,and the present reaction did not require an addition of any oxidant,avoiding the use of traditional heating and polluting oxidants.The reaction process and the post-treatment are simple and safe.The obtained results showed that the optimal reaction conditions were as follows:acetonitrile/water(3 mL/5 mL)as the solvent,75 W light irradiation and 365 nm wavelength of light.The highest conversion of the raw material is 100％,and the highest yield of the target product is 92％.
