Role of N-ZnO/GO and Fe2O3-ZnO in photocatalytic activity

Present research work reports the synthesis of visible light-active ZnO photocatalyst through modification with N/GO and Fe2O3/GO. Modified ZnO samples are characterized by XRD. Photocatalytic activities of samples are measured in waste water consist of organic pollutants such as Malachite green (MG). N-ZnO/GO samples exhibited better photocatalytic degradation as compare to Fe2O3 doped ZnO. Dye degradation follow first order kinetic and rate constants are also measured.
