Fenton-like catalytic oxidation of o-cresol wastewater by H₂O₂ over Fe₂O₃/AC catalysts

A series of high specific surface Fe₂O₃/AC catalysts for the Fenton-like catalytic oxidation of o-cresol wastewater was designed. The catalytic performance due to the characteristics of high specific surface area, large pore volume, high chemical stability and dispersive activity center. Under the suitable reaction conditions, the Fe₂O₃/AC with 3 wt.% Fe₂O₃ loading catalyst can run efficiently and continuously for 500 h without being deactivated, meanwhile the removal efficiency of COD can still be maintained above 59%, even the activity of the catalyst can remain above 79%. As a result, this kind of high specific surface Fe₂O₃/AC catalysts used in the heterogeneous Fenton-like catalytic oxidation of o-cresol wastewater has a great potential for industrial application.
