The nitrogen-self-doped three-dimensional graphene-like networks (N-3D GNs) with suitable surface areas and hierarchical porous structures have been synthesized by an improved ion-exchange/activation method. The Pt nanoparticles supported on N-3D GNs give more than double mass activity and almost no degradation in surface area after 5000 cycles compared with a commercial Pt/C catalyst. The results demonstrate that the improvement in the support can reach 2.6 times the catalytic activity. This strategy is a direct way to reduce the catalyst cost and make the practical application of the catalyst a reality.
