The Ag3PO4 crystal with 200-600 nm in diameter was successfully synthesized using co-precipitation method with AgNO3 and Na2HPO4.12H2O as starting materials. The product was characterized using XRD, DRS, FTIR and SEM. The photocatalytic activities were evaluated under blue light irradiation assisted by Fe2+. The 1 mL of Fe2+ aqueous solutions consisted of 1.00, 0.10, 0.01, 0.001 and 0.0001 mM Fe2+ was added into a 100 mL solution of Rhodamine B, and the photocatalytic oxidation of Rhodamine B was carried out under visible light irradiation. The highest photocatalytic activity was observed when 1 ml of 0.001 mM of Fe2+ aqueous solution was added in the Rhodamine B solution. The result inferred the possibility of in-situ peroxide generation during the photocatalysis reaction.
