石墨烯的化学研究进展

Progress in graphene chemistry

评述了近3年来在石墨烯(graphene)制备化学、石墨烯化学改性、石墨烯表面化学和催化等方面取得的重要进展.阐述了通过化学方法实现非支撑(freestan ding)或准非支撑(quasifree-standing)石墨烯结构的可控和规模制备;通过表面反应对石墨烯进行掺杂和官能化,制备了石墨烷、石墨烯氧化物等具有特殊结构和性质的石墨烯相关化合物;这些石墨烯及石墨烯相关材料(graphene and related materials)在催化、储氢等领域展现出非常重要的应用前景.

Graphene has been extensively studied in the past five years, in particular, in the field of physics. In the present review, we intend to summarize the recent progress in graphene chemistry, which has attracted increasing attention in the past three years. First, a summary is presented about the major progress on chemical routes to graphene, showing that graphene with controlled size, thickness, and electronic structure could be obtained by chemical methods, such as chemical vapor deposition. Then, the progress in functionalization, surface modification, and doping of graphene is highlighted. The graphene related materials, such as graphene oxide, graphane, N-doped graphene, have been synthesized and they display many unique physic-chemical properties. Finally, applications of graphene and the graphene related materials in chemistry, particularly, in catalysis, were described.
