▎ 摘　　要

NOVELTY - Fenton catalyst comprises graphene as carrier and aminobenzene tripyridine iron complex as Fenton reagent. The graphene is connected with complex through covalent bond. The mass fraction of iron in catalyst is 5-10 wt.%. USE - The Fenton catalyst is used for covalent grafting of graphene onto aminobenzene tripyridine iron complex (claimed). ADVANTAGE - The Fenton reagent overcomes iron ion loss and secondary pollution, has higher electron transfer efficiency, larger specific surface area of graphene, high degradation efficiency, good stability and 100% degradation rate of 100 mg/L rhodamine B in 60 minutes, enhances degradation ability of organic pollutants and does not decrease degradation rate after 5 cycles.
