A facile, in situ plasma synthesis of surface functionalized graphene-based Pt nanoparticles has been achieved. The H-doped graphene (GH) and N-doped graphene (GHA) were prepared by reduction of grapheme oxide (GO) in hydrogen and ammonia plasma, respectively. The GH-based Pt NPs (Pt/GH) and GHA-based Pt NPs (Pt/GHA) were prepared by simultaneous reduction of GH and H2PtCl6 or GHA and H2PtCl6 under hydrogen plasma, respectively. The electrocatalytic activity of the Pt/GH and Pt/GHA were studied.
