In the field of photocatalysis,silver phosphate(Ag_(3)PO_(4)),a prominent visible-light-driven semiconductor photocatalytic material,has garnered significant attention due to its suitable bandgap properties and excellent quantum efficiency,enabling it to efficiently degrade organic pollutants,produce hydrogen via water splitting,and exhibit strong antibacterial effects under visible light irradiation.Current core research directions for Ag_(3)PO_(4)-based photocatalysts focus on further enhancing light absorption capacity,optimizing charge carrier separation efficiency,and addressing the issue of photocorrosion.This review systematically analyzes the photocatalytic mechanism of Ag_(3)PO_(4)based on its physicochemical properties,revealing the dynamic processes of photogenerated charge carriers and the principles of recombination suppression.By comparing various synthesis methods,including precipitation,colloid,hydrothermal,solid-phase grinding,and chemical oxidation methods,their impacts on the morphology and performance of Ag_(3)PO_(4)are discussed.To tackle bottlenecks such as low charge carrier mobility and photocorrosion,multidimensional modification strategies are proposed,including morphology regulation,ion doping,defect engineering,and construction of semiconductor heterojunctions.The underlying mechanisms by which these strategies enhance the performance of Ag_(3)PO_(4)-based photocatalysts are also elucidated.Additionally,the review summarizes the application fields of Ag_(3)PO_(4)-based materials and prospects their potential in environmental governance,energy conversion,sterilization,and disinfection,providing critical references and guidance for future in-depth research and broad applications of this material.
