A large quantity of highly conductive graphene was prepared by a novel CVD method with nickel powder as a template and PMMA as carbon source. With Pt as a model, PtNP–modified graphene showed much better electrocatalytic ability for O2 and methanol than PtNP–reduced graphene oxide (RGO) and commercial Pt/C, showing that this graphene is a better catalyst carrier than RGO and commercial carbon.
