中文摘要：开发高效稳定的半导体光催化剂对光催化技术迈向实际应用至关重要.聚合物氮化碳(CN)因其优异的物理化学性质而被视为最具发展前景的制氢光催化剂之一.在过去几十年中,从热力学或动力学角度开发的一系列改性策略已经显著提升了CN的光催化制氢性能.近期,金属原子修饰策略为CN改性提供了一条新途径,这种策略可以精确调控CN的微环境.本文全面回顾了金属原子修饰的CN光催化剂在光催化分解水制氢领域的最新研究进展,包括金属单原子修饰的CN、金属双原子修饰的CN、金属单原子与团簇共修饰的CN,重点阐述了金属原子对提升光催化性能的关键作用.此外,本文还全面总结了发展先进的金属原子修饰的CN光催化剂所面临的挑战与机遇.

外文标题：Metal atom-induced microenvironment regulation in polymeric carbon nitride for photocatalytic hydrogen evolution

外文摘要：Developing high-efficiency and stable semi-conductor 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 op-portunities in the development of advanced CN-supported metal atom photocatalysts are thoroughly summarized.
