The visible-light responsive semiconductor carbon nitride (C₃N₄) exhibits suitable electronic band structure, rich sources of precursors, and high stability, which is exploited to satisfy energy demands. However, the photocatalytic efficiency of C₃N₄ is limited because of its low surface area and low separation and transfer efficiency of charge carriers. As Z-scheme strategy can effectively help C₃N₄ overcome its instinct shortage, this review will outline the recent significant progress on the development of C₃N₄-based all-solid Z-scheme photocatalysts for energy-conversion applications including water splitting and CO₂ reduction. In the beginning, the fundamental principles of Z-scheme will be introduced, especially for all-solid-state system. Then, the comprehensive account of the development of C₃N₄-based Z-scheme photocatalysts are discussed. Finally, perspectives on the challenges and future directions at the forefront of Z-scheme photocatalysts are provided.

用于太阳能转换应用的氮化碳基全固态 Z 型光催化剂的开发新进展

可见光响应半导体氮化碳（C ₃ N ₄）具有合适的电子能带结构、丰富的前体来源和高稳定性，可满足能源需求。然而，C ₃ N ₄的光催化效率因其表面积低和载流子分离和转移效率低而受到限制。由于Z-scheme策略可以有效地帮助C ₃ N ₄克服其本能短缺，本综述将概述最近在C ₃ N ₄基全固体Z-scheme光催化剂的开发方面取得的重大进展，该催化剂用于包括水分解在内的能量转换应用和一氧化碳₂减少。首先介绍Z-scheme的基本原理，特别是对于全固态系统。然后，综合论述了基于C ₃ N ₄的Z 型光催化剂的发展。最后，提供了 Z 型光催化剂前沿面临的挑战和未来方向的观点。
