摘要 PtSn2-SnO2/C nanocatalyst was prepared by co-reduction of Pt and Sn precursor at ca,15℃.The formation of PtSn2-SnO2 nanoparticle was determined by XRD,TEM and XPS characterization.This PtSn2-SnO2/C nanocatalyst exhibits stronger resistance to CO poisoning and effectively improves methanol electro-catalytic effect,up to 3 times than the commercial Pt/C catalyst.
