Catalytic wet hydrogen peroxide oxidation of H-acid in aqueous solution with TiO2-CeO2 and Fe/TiO2-CeO2 catalysts

►The activity of TiO2-CeO2 catalysts was strongly affected by Ti/Ce molar ratio. ►Fe loading could obviously improve the activity of TiO2-CeO2 catalyst, and the optimum Fe loading content was 2%. ►35.8% and 65.4% TOC removals were obtained with TiO2-CeO2 (Ti/Ce 9/1) and the Fe/TiO2-CeO2 (Ti/Ce 9/1, 2% Fe) in CWPO of H-acid.
