▎ 摘　　要

Graphene is a hot topic in many research fields due to its outstanding physicochemical properties. It is also a new carbon catalyst support after activated carbon, carbon nanotube, fullerene and mesoporous carbon. In the present article, we focused on the application of graphene in the field of catalytic hydrogenation, summarized the preparation and characterization of graphene, and discussed the advantages and disadvantages of graphene as a catalyst support and metal-free catalyst. Some factors that may affect the catalytic hydrogenation activity have also been discussed in detail. (C) 2016 Published by Elsevier B.V. on behalf of Taiwan Institute of Chemical Engineers.
