Abstract:Ag₃PO₄ is found to be a highly efficient photocatalyst and receives great attention. The high activity of the photocatalyst is credited to the intrinsic electronic structure. The morphology control and nano-composite fabrication are used to improve the performance and practicability. This paper reviews the structure, properties and some theoretical aspects of Ag₃PO₄ single crystal. Also, the major strategies, namely the morphology control and hetero-nanostructure construction, as ways to improve the performance of Ag₃PO₄-based photocatalysts, are summarized with the aid of some typical instances.

Key words: Ag₃PO₄-based photocatalyst; electronic structure; morphology control; hetero-structure construction; preparation; photocatalytic activity
