▎ 摘　　要

Graphene nanosheets loading with high density Pt nanoparticles have been successfully fabricated with a facile one-pot method. Firstly, Fe2+ was selectively adsorbed onto the surface of grapheme oxide (GO) via the electrostatic attraction with oxygenate groups of GO. Secondly, Fe2+ bonded with oxygenate groups of GO as binder adsorbed negatively charged PtCl62-. The high density Pt-graphene composite nanosheets were applied in methanol eletro-oxidation.
