Here we reported an effective method to solve the rate-limiting steps,such as the reduction of Fe3+ to Fe2+ and an invalid decomposition of H2O2 in a conventional Fenton-like reaction.A magnetic heterogeneous photocatalyst,Fe3O4-schwertrnannite (Fe3O4-sch) was successfully developed by adding Fe3O4 in the formation process of schwertmannite.Fe3O4-sch shows excellent electrons transfer ability and high utilization efficiency of H2O2 (98.5％).The catalytic activity of Fe3O4-sch was studied through the degradation of phenol in the heterogeneous photo-Fenton process.Phenol degradation at a wide pH (3-9) was up to 98％ within 6 min under visible light illumination with the Fe3O4-sch as heterogeneous Fenton catalyst,which was higher than that using pure schwertmannite or Fe3O4.The excellent photocatalytic performance of Fe3O4-sch is ascribed to the effective recycling between ≡Fe3+ and ≡Fe2+ by the photo-generated electron,and also profit from the formation of the “Z-Scheme” system.According to the relevant data,photocatalytic mechanism of Fe3O4-sch for degrading phenol was proposed.This study not only provides an efficient way of enhancing heterogeneous Fenton reaction,but also gives potential application for iron oxyhydroxysulfate mineral.
