Preparation of PtSn2–SnO2/C nanocatalyst and its high performance for methanol electro-oxidation

PtSn2–SnO2/C nanocatalyst was prepared by co-reduction of Pt and Sn precursor at ca.15 °C. 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.
