Abstract

The influence of the SnO₂ proportions on the activity of Pt/C+SnO₂ catalysts was examined. The results verified that Pt particles were evenly spread on the carriers. The Pt/C+SnO₂ catalysts demonstrated better electrooxidation activity than the Pt/C. The SnO₂ could carrier OH_ads groups. The OH_ads promoted the oxidation of CO_ads and released the Pt active sites. The Pt/C+SnO₂ catalyst with 20 % (mass) SnO₂ demonstrated the excellent activity and stability for Di-Methyl Ether (DME) oxidation. Excessive SnO₂ might hide the active sites of Pt, which would lead to the decrease of catalyst performance.
