- ... Graphite oxide (GO) with varied oxidation degrees and hexachloroplatinic acid were used as precursors for the synthesis of Pt/graphene composites via a polyol approach. It is revealed that the epoxy-rich basal planes of GO serve as the active sites for the nucleation of Pt nanoparticles via COPt bonds. With the increased oxidation degree of GO, both the nucleation sites and the repulsive forces be ...
