Application of Ce-Ag-ZnO Nano-Photocatalyst For Textile Wastewater Treatment

The synthesis of Ce co-doped Ag–ZnO (Ce–Ag–ZnO) has been successfully achieved by a microwaveassisted solution combustion method. The synthesized catalyst was characterized by X-ray diffraction (XRD), fieldemission scanning electron microscope (FE-SEM) images. The photocatalytic activity of Ce–Ag–ZnO was investigatedfor the degradation of Reactive Red 120 dye in aqueous solution under uv illumination in a semi-batch reactor. Maximumremoval of 97% was achieved for the 20 mg/l Reactive red 120 solution at pH=7 and catalyst dose= 0.1 g/l andtime =60 min. This study showed that silver and cerium have a significant role in improving ZnO photocatalytic activity.
