Ag3PO4 and Ag3PO4–based visible light active photocatalysts: Recent progress, synthesis, and photocatalytic applications

Photocatalysis has been regarded as one of the promising technologies in treating pollutants. Visible light-driven photocatalysis has attracted attention due to its potential in utilizing a greater portion of sunlight. Silver phosphate (Ag3PO4) is a visible light active photocatalyst that exhibited 90% quantum efficiency and showed excellent photocatalytic performance in decomposing pollutants. This review provides an overview of the selection of suitable synthesis methods used to obtain desirable Ag3PO4 and Ag3PO4-based for different types of photocatalytic applications utilizing visible light. The challenges and the prospects of improving the performance of Ag3PO4 and Ag3PO4-based visible light active photocatalysts have been discussed.
