摘　　要：石墨相氮化碳是一种不含金属的半导体聚合物材料,具有独特的物化性质和电子结构,在多相催化加氢等领域具有重要的应用前景。文章主要介绍了目前常用于制备石墨相氮化碳的主要方法(即硬模板法、软模板法和无模板法)以及通过杂原子掺杂(非金属原子/金属原子)和其他材料复合的修饰改性方法。在此基础上,综述了以石墨相氮化碳为载体所制备的负载型金属催化剂及其在精细化学品、C1分子、烯烃、炔烃分子催化加氢反应方面的研究进展,并对相关领域的关键问题和未来发展趋势进行了展望。Graphitic carbon nitride(g-C3N4)is a metal-free polymeric semiconductor material and has unique physicochemical properties and electronic structure,and has great application potential in heterogeneous catalytic hydrogenation in recent years.This paper introduced main preparation methods of g-C3N4(e.g.hard template method,soft template method and template-free method)and the modification methods(e.g.doping with non-metal atoms/metal atoms and compounding with other materials).It also summarized the recent progresses in the application of g-C3N4 supported metal catalyst in the catalytic hydrogenation of fine chemicals,C1 molecules,alkenes and alkynes,and discussed the development trend and key problems in the related field.
