In this study Fe3O4-ZnO and GO-Fe3O4-ZnO are synthesized as photocatalysis for decomposition of of methyl orange (MO) as organic dye pollutant model. The XRD results show that the prepared nanocomposites contain the modified GO with cubic structure of Fe3O4 and hexagonal wurtzite structure of ZnO nanoparticles. The photocatalytic results show that the degradation of MO using both of the synthesized photocatalysts enhances with respect to the time and weight fraction. The removal efficiency of MO using GO-Fe3O4-ZnO at each concentration and irradiation time is more than that of Fe3O4-ZnO.
