Abstract

Developing high-efficiency and stable semiconductor photocatalysts is crucial for realizing the practical applications of photocatalysis. Polymeric carbon nitride (CN) has been verified as a promising candidate for photocatalytic H₂ evolution due to a series of outstanding physicochemical properties. Over the past decade, significant progress has been made in enhancing the photocatalytic H₂ evolution of CN-based photocatalysts through various strategies based on thermodynamics or kinetics. Recently, metal atom decoration has provided a new avenue for modifying CN by precisely regulating its microenvironment. This paper provides a comprehensive review of recent advancements in metal atom-decorated CN photocatalysts for photocatalytic H₂ evolution via water splitting, encompassing single metal atom decorated CN, dual metal atoms decorated CN, and single metal atom and cluster co-decorated CN, in which the vital roles of metal atoms are highlighted. Furthermore, the challenges and opportunities in the development of advanced CN-supported metal atom photocatalysts are thoroughly summarized.

用于光催化氢进化的聚合氮化碳中金属原子诱导的微环境调节

开发高效稳定的半导体光催化剂对于实现光催化的实际应用至关重要。高分子氮化碳（CN）具有一系列优异的物理化学特性，已被证实是光催化 H2 演化的理想候选材料。在过去的十年中，通过基于热力学或动力学的各种策略，在提高 CN 基光催化剂的光催化 H2 进化方面取得了重大进展。最近，金属原子装饰为通过精确调节 CN 的微环境来改性 CN 提供了一条新途径。本文全面综述了金属原子装饰的 CN 光催化剂在通过水分裂光催化 H2 演化方面的最新进展，包括单金属原子装饰的 CN、双金属原子装饰的 CN 以及单金属原子和团簇共装饰的 CN，其中强调了金属原子的重要作用。此外，还深入总结了开发先进的 CN 支持金属原子光催化剂所面临的挑战和机遇。
