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

Abstract

A series of high specific surface Fe _2 O _3 /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 Fe _2 O _3 /AC with 3 wt.% Fe _2 O _3 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 Fe _2 O _3 /AC catalysts used in the heterogeneous Fenton-like catalytic oxidation of o-cresol wastewater has a great potential for industrial application.
