Catalytic oxidation degradation of phenol in wastewater by heterogeneous Fenton reagent

Heterogeneous Fenton reagent, as a strong oxidizer, has been used widely in the treatment of wastewater. We prepared Fe2O3/γ-Al2O3 catalyst by impregnation method and characterized it by powder X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM). Test results show that Fe2O3 crystal was compounded on the γ-Al2O3 carrier. We tested and optimized Fe2O3/γ-Al2O3/H2O2 and Fe2O3/γ-Al2O3/H2O2 /UV...
