A novel Ag3AsO4 visible-light-responsive photocatalyst: facile synthesis and exceptional photocatalytic performance.

A novel Ag3AsO4 photocatalyst has been prepared via a facile precipitation method. It exhibited higher activity than Ag3PO4 or AgI in degradation of rhodamine B or methyl orange. The excellent activity of Ag3AsO4 is attributed to its more separated photogenerated carriers and high absorption capacity of visible light.
