▎ 摘　　要

Metal-free carbon catalysts have been receiving increasing attention in the fields of nanomaterials and catalysis. Compared with conventional metal catalysts, there are many advantages for metal-free carbon catalysts, such as simple synthesis, stable structure, large surface area, and diverse applications. Graphene is one layer of carbon atoms and has a periodic structure of aromatic carbon atoms. Graphene oxide is a highly oxidized form of graphene. As a new carbon material, its application in catalysis has emerged over the past 5 years. Graphene-based materials can efficiently catalyze hydrocarbon conversion, organic synthesis, energy conversion, and other heterogeneous catalytic processes. This review highlights the recent progress in the development of metal-free graphene-based catalysts (graphene oxide and graphene) and associated catalytic reactions.
