文摘

Tungsten carbide nano powder was synthesized using acetone as carbon source. In-situ produced outer carbon layer increase the surface area of materials. Mesoporous WC with surface areas 52.6 m2/g obtained. Pt modified WC powder showed higher electrochemical stability. Better CO-tolerance for ethanol oxidation after the deposition of Pt nano particles.
