Enhanced electrocatalytic performance of Pt-based nanoparticles on reduced graphene oxide for methanol oxidation

► PtM (M = Sn, W and Mo) catalysts supported on RGO were in situ fabricated. ► The catalytic activity of RGO/PtM toward methanol oxidation reaction was studied. ► The RGO/PtM exhibited higher catalytic activity and stability than RGO/Pt catalyst. ► The addition of M can create much more Pt active sites for methanol oxidation.
