摘　　要：由于高的比表面积、可调的孔隙结构以及易于修饰的表面化学性质,纳米碳材料作为催化剂和催化剂载体(碳基催化剂)被广泛地应用于多相催化领域.新型的金属和氮共修饰的碳材料(M-N-C)作为非均相催化剂在许多反应(如加氢/氢转移、加氢脱氧、氧化反应)中表现出了优异的催化性能.从结构上讲, M-N-C催化剂可以分为负载型催化剂(M/CN)、金属单原子分散型催化剂(M_(SAC)/CN)和包覆型催化剂(M@CN).本文围绕本课题组近些年取得的研究进展,重点介绍了M@CN催化剂的结构、性质、制备方法及其在催化反应(包括加氢、氢转移、氧化)中的应用,为从分子层面设计新型的非均相催化剂提供了思路借鉴,并对未来的研究方向和发展趋势进行了展望.Nanocarbon material as catalyst and catalyst support(carbon-based catalyst) has been widely used in heterogeneously catalytic fields, due to its high surface area, tunable porous structure and easily modified surface chemical property. Metal and nitrogen co-modified carbon material(M-N-C) as heterogeneous catalyst exhibits excellent catalytic performance in the hydrogenation/transfer hydrogenation, hydrodeoxygenation and oxidative reaction. From the structure of M-N-C catalyst perspective, it contains carbon supported catalyst(M/CN), single atom catalyst supported on carbon(MSAC/CN) and nitrogen-doped carbon coating metal catalyst(M@CN). In this feature article, we focus on the introduction for the structure, property, synthesis methods of M@CN catalyst and its application in the heterogeneous reaction(hydrogenation, transfer hydrogenation, oxidation) around the achievement of our group,in order to provide ideas for the design of new heterogeneous catalysts.
