AbstractSurface modification of Ag3PO4 using alginate has been successfully synthesized. Ag3PO4 was prepared by precipitation method using CaHPO4/hydroxyapatite composite as a source of phosphate ion and AgNO3 ethanol solution. Alginate was introduced on the surface of Ag3PO4 under the chemisorption method. Products were analyzed using XRD, DRS, PL spectra, FTIR, SEM, TEM, and XPS. A small band edge absorption at 729 nm was created after surface modification using alginate. XPS analysis showed that the binding energy shifts of 0.3 eV and 0.5 eV were observed after alginate treatment for Ag3d and P2p respectively indicating that the alginate was successfully chemically bound to the Ag3PO4 surface. The alginate-modified Ag3PO4 photocatalyst showed much higher photocatalytic activity than pure Ag3PO4. The high activity is caused by the formation of conjugates that can act as electron donors under visible light irradiation.
