Effect of CeO2 doping on catalytic activity of Fe2O3/γ-Al2O3 catalyst for catalytic wet peroxide oxidation of azo dyes

In order to find a catalyst with high activity and stability for catalytic wet peroxide oxidation (CWPO) process under normal condition, with Fe2O3/γ-Al2O3 and Fe2O3–CeO2/γ-Al2O3 catalysts prepared by impregnation method, the effect of CeO2 doping on the structure and catalytic activity of Fe2O3/γ-Al2O3 for catalytic wet peroxide oxidation of azo dyes at 25 °C and atmospheric pressure is evaluated using BET, SEM, XRF, XRD, XPS and chemical...
