The synthesis of high performance catalysts for the catalytic wet oxidation (CWO) N-methyldiethanolamine (MDEA) in water remains a challenge, and is topic considerable importance relation to sustainability. In this paper, Ru-CNx/CeO2 catalyst was synthesized through modified impregnation process CWO MDEA, exhibiting activity 80% COD removal at 180 °C 2.5 MPa. EPR, Raman, XPS characterizations revealed that CNx species facilitated reduction Ru4+ Ru0 enhanced Ru–Ce interaction form high-density Ru-O-Ce structure with Ce3+ sites, which strongly correlate generation oxygen vacancies. vacancies enabled adsorption activation oxygen, generating active (h+, ·O2−, ·OH) effectively oxidized MDEA during reaction.
