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.
