▎ 摘　　要

As a novel carbon nanomaterial, graphene based composite has received much attention in catalysis due to its unique characterisics such as large surface area, good thermal and chemical stability, strong hydrophobicity, easy modification, etc. Graphene and its composites have been applied in the catalysis of different organic reactions, such as Suzuki-Miyaura, Heck, and reduction of nitroarenes. The research progress of graphene-based composites catalyst is briefly reviewed in the paper.
