Delafossite-alumina nanocomposite for enhanced catalytic wet peroxide oxidation of anionic pollutants.

Mass transfer efficiency and catalytic reactivity are the two major hurdles for heterogeneous catalytic wet peroxide oxidation (CWPO) technologies. To address these issues, nanocomposite CuFeO/AlO was synthesized and assessed as a novel catalyst for enhanced adsorption and oxidation of anionic pollutants (catechol and reactive red 195 (RR195)) in waters. With a positive charge on the nanocomposite by introducing AlO, the adsorption of anionic pollutants was promoted.
