▎ 摘  要

In this communication, a synergistic interaction of the grapheneamorphous carbon (CG) nanohybrid support framework is configured, leading to excellent activity and stability in polymer electrolyte fuel cells. Graphene-amorphous carbon nanohybrid-Pt matrix is synthesized by a versatile chemical method. The optimum composition of CG nanohybrid with thin Pt loading of 50 mu g cm(-2) shows excellent catalytic activity. Besides, synergistic interaction between graphene and amorphous carbon nanohybrid results in enhanced stability of Pt and retains about 50% initial performance even after 5000 cycles.
