Abstract/OtherAbstract:
Abstract Promotion of the dispersion of Ru species supported on TiO2 was achieived by introduction of Pt component and the role of Pt in enhancing the catalytic performances of Pt-Ru were investigated with catalytic wet air oxidation (CWAO) of methylamine (MA) used as a probing reaction. It was found that Pt-Ru/TiO2 displyed much better catalytic performance compared to Pt/TiO2 and Ru/TiO2 catalysts due to having the highest dispersion of active species. Both high TOC conversion and nitrogen selectivity (∼100%) over Pt-Ru/TiO2 catalyst were achieved at low temperature (200 ℃). XPS characterization indicated that there were strong interactions between metal particles and the support, which may increase the catalytic performance of catalysts. Supplementary material.
