摘要
Abstract
Photocatalytic production of hydrogen peroxide(H2O2)has broad application prospects in converting solar energy into chemical energy.However,the traditional powder catalyst is faced with problems such as difficult recovery and secondary pollution.PVC/ZnO composite film for photocatalytic H2O2 generation was prepared by loading ZnO photocatalyst on PVC film,and its photocatalytic performance,catalytic mechanism and stability were studied.The results show that the PVC/ZnO-0.4 composite film exhibites the best photocatalytic performance,and the cumulative concentration of H2O2 reaches 165.15 μmol/L within 60 min.The catalytic mechanism study shows that the two-electron oxygen reduction produces H2O2.The study of cycle stability shows that the PVC/ZnO composite film has excellent cycle performance and stability.The prepared PVC/ZnO composite photocatalytic film can effectively avoid catalyst loss,thereby improving the overall catalytic performance of the photocatalytic material.关键词
