Facile synthesis of tetrahedral Ag3PO4 submicro-crystals with enhanced photocatalytic properties

Tetrahedral Ag3PO4 submicro-crystals have been fabricated in high-yield by directly reacting commercial Ag foils with H2O2 and NaH2PO4 in aqueous solution at room temperature, which exhibit higher photocatalytic activities than Ag3PO4 cubes, particles, and N-doped TiO2 for the degradation of organic contaminants under visible light irradiation.
