摘要 新型单原子光催化剂因具有较强的光催化活性、选择性、原子利用率而在光催化领域备受关注,但表面自由能高、结构不稳定等缺陷导致其实际应用时受到诸多限制。随着光催化剂制备技术的快速发展,将金属单原子锚定到石墨氮化碳(g-C3N4)上制备的光催化剂被发现同时具有成本低、导电性好、制备简便、结构稳定、吸附性能好、电子-空穴分离转移效率高等诸多优点,可有效解决前述问题,目前已在制氢、二氧化碳还原、氢化反应中得到广泛应用,但在高效降解水体各类有机污染物方面的研究相对有限。鉴于此,本文聚焦金属单原子/g-C3N4,详细介绍了单原子(主要为金属原子)/g-C3N4的合成方法,分析和讨论了不同类型单原子与g-C3N4之间的作用机理,综述了其在光催化降解抗生素、染料和酚类物质等领域的应用进展,对应用中遇到的问题进行了详细讨论并给出了相应建议。此外,展望了未来金属单原子/g-C3N4催化剂的研发、生产及水污染修复应用前景。

Abstract: Novel metallic single-atom photocatalysts have attracted much attention in the photocatalytic field due to their strong photocatalytic activity, selectivity, and atom utilization. However, its defects such as high surface free energy and unstable structure lead to many limitations in the practical application of photocatalysis. With the rapid research and development of photocatalyst preparation technology, it has been found that the photocatalysts prepared by anchoring metallic single atoms to graphitic carbon nitride (g-C3N4) exhibit simultaneously multiple advantages, such as low cost, good electrical conductivity, easy preparation, structural stability, good adsorption performance, and high efficiency of electron/hole separation and transfer, which can effectively solve the aforementioned problems. At present, this type of catalyst has found widely application in hydrogen production, carbon dioxide reduction, and hydrogenation reactions, but research on efficient degradation of various organic pollutants in water is relatively limited. In view of this, this paper takes metallic single atoms/g-C3N4 as the research object, describes the synthesis method of single atoms (mainly metal atoms)/g-C3N4 in detail, analyzes and discusses the action mechanism between different types of single atoms and g-C3N4, and reviews its progress of its application in the fields of photocatalytic degradation of antibiotics, dyes and phenol, and also provides detailed discussion and suggestions on the problems encountered in the practical application in this field. The progress of its application in the fields of photocatalytic degradation of antibiotics, dyes and phenolics is summarized, and the problems encountered in the practical application in this field are discussed in detail and the relevant suggestions are given.
