Abstract Replacement of precious metal catalysts by commercially available alternatives is of great importance among both fundamental and practical catalysis research. Nanostructured carbon and graphene-based materials demonstrated promising catalytic properties in a wide range of energy generation/storage applications. Specifically engineering graphene and porous carbon with guest atoms can improve its catalytic activity for electrochemical oxygen reduction reaction (ORR), oxygen evolution reaction (OER) and hydrogen evolution reaction (HER),thus can be considered as potential substitutes for the expensive Pt/C catalyst in fuel cells or metal-air batteries etc. In this presentation, we will talk about the synthesis ofmetal free elements-doped graphene (B,N-graphene, S,N-graphene), 3-D porous g-C3N4@Carbon materials and other materials,as well as their application on electrocatalysis. The excellent ORR, OER and HER performance (high catalytic activity andefficiency)and reliable stability (much better than the commercial Pt/C) indicate that new materials are promising candidates for the next generation of highly efficient electrocatalysts. We will also briefly introduce our work on the synthesis of other carbon-based materials and their applications on energy storage and conversion.
