摘要: Pt-Ru, Pt and Ru catalysts supported on zirconia were prepared by impregnation method and were tested in selective oxidation of methylamine (MA) in aqueous media. Among three catalysts, Ru/ZrO2 wasmore active than Pt/ZrO2 while Pt-Ru/ZrO2 demonstrated the best catalytic activity due to the fact that Pt addition efficiently promoted the dispersion of active species in bimetallic catalyst. Therefore, the ~100% TOC conversion and N2 selectivity were achieved over Pt-Ru/ZrO2, Pt/ZrO2 and Ru/ZrO2 catalysts at 190, 220 and 250 ℃, respectively.
