Abstract: The organic dye pollutants such as Congo red (CR) and Eosin yellow (EY) contaminate the water. Hence there is need to develop composite for removal of dyes. In this manuscript, we reported the reduced graphene oxide based zinc oxide (ZnO/RGO) nanocomposite (NC) was synthesized by simple and green hydrothermal method. As-prepared nanocomposite was characterized by XRD, FESEM, EDS, TGA, FTIR and UV-DRS to study its structure, morphology and thermal stability. As synthesized composite was executed excellent photocatalytic activity by the degradation of organic dye pollutants, CR and EY under visible light irradiation. The effect of pH, concentration dye solution and catalyst dose were studied to optimise. The optimised conditions for degradation of CR using ZnO/RGO composite are 0.05g catalyst dose, pH-3 and initial concentration 10 ppm of dye solution. From these results, this composite served as benign photocatalyst for completely degraded CR in 120 min and EY in 100 min respectively.
