光催化制氢在清洁能源和可持续能源的开发中起着至关重要的作用。二维石墨氮化碳（g-C3 N4）由于其特殊的结构和特性，引起了人们的极大关注。然而，天然g-C3 N4的一些缺陷限制了其光催化应用，特别是析氢量子效率较低。因此，开发基于g-C3 N4的二维新型复合材料，以实现两种原始材料的协同效应是有价值的。本文从异质结的构建、形貌控制、掺杂方法、表面改性以及助催化剂的负载等方面综述了2D g-C3 N4基复合材料的改性策略。介绍了光催化制氢技术的应用和进展。考虑到的限制，以提供进一步的信息，通过二维g-C3 N4基复合材料的氢的量子效率的改善。
Photocatalytic hydrogen evolution plays a critical role in the exploration of the clean and sustainable energy. Owing to its special structure and features, two-dimensional (2D) graphitic carbon nitride (g-C3N4) has attracted tremendous attention. However, some deficiencies of pristine g-C3N4inhibit its photocatalytic application, particularly the low quantum efficiency of hydrogen evolution. Therefore, it is valuable to develop 2D new composites based on g-C3N4so that the synergistic effects of the two original materials can be achieved. This article attempts to summarize the modification strategies of 2D g-C3N4-based composites, including the construction of heterojunctions, morphology control, doping method, surface modification and co-catalyst loading. The application and progress in photocatalytic hydrogen evolution are also highlighted. The limitations are taken into account to provide further information for the improvement in the quantum efficiency of hydrogen by 2D g-C3N4-based composites.
