摘要
石墨相碳化氮(g-C_(3)N_(4))因带隙窄、电子结构独特、稳定性高、廉易得等优点成为光催化领域的研究热点。然而,原始氮化碳往往存在比表面积小、光响应范围窄、电子-空穴易复合等缺点。特殊结构g-C_(3)N_(4)具有多级结构,可以调节载流子迁移路径,是显著提高g-C_(3)N_(4)比表面积、改善其电子结构,促进电荷分离的有效手段。本文综述了不同结构和形貌的g-C_(3)N_(4)及其复合体系的研究进展,并对不同形貌g-C_(3)N_(4)的构效关系进行了分析,展望了未来g-C_(3)N_(4)的研究方向和应用前景。
Graphite phase nitrogen carbide(g-C_(3)N_(4))has grown as a research hotspot in the field of photocatalysis due to its narrow band gap,unique electronic structure,high stability,and easy availability.However,the pristine carbon nitride also has its disadvantages,such as:the small specific surface area,narrow light response range,and easy electron-hole recombination.The multi-stage structures of special g-C_(3)N_(4)have an adjustable carrier migration path,which was effective means to significantly improve the specific surface area,electronic structure,and charge separation of g-C_(3)N_(4).This review highlighted the research progress of special morphologies of g-C_(3)N_(4)and its composite system,the structure-performance relationship of g-C_(3)N_(4)with different morphologies and prospects was analyzed for the research direction of g-C_(3)N_(4)in the future.
