Photocatalytic removal of organic water pollutants as a green method, one of the most important issues that have drawn wide attention since 2010. In this dissertation, photocatalytic properties of graphene-phosphate, silver-zinc phosphate nanocomposites, and effect simultaneous presence of reduced graphene oxide and graphene oxide were investigated to removed organic pollutant. First, the synthesis of graphene oxide was synthesized by the Hammers' method. Co-precipitation and hydrothermal methods were used to prepare nanocomposites. Effect of the simultaneous presence reduced graphene oxide and graphene oxide Was evaluated with two types of reduced graphene oxide: In-situ synthesize (by hydrothermal method) and commercially reduce reduced graphene oxide. XRD, FT-IR, Raman spectroscopy, UV-Vis DRS, UV-Vis, PL, and FE-SEM were used. Degradation of Methylene blue was performed in all samples except Zn3(PO4)2 do to wide it's band gap about 3.04 eV. The band gap were abtained about 2.34, 2.57, and 2.42 in Ag3PO4 and GO/Ag3PO4/Ag for Two samples synthesized by hydrothermal method at 60°C and 180°C , respectively.
