摘要

Abstract

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/ZrO

wasmore active than Pt/ZrO

while Pt-Ru/ZrO

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 N

selectivity were achieved over Pt-Ru/ZrO

Pt/ZrO

and Ru/ZrO

catalysts at 190

220 and 250 ℃

respectively.
