Rhodamine B Dye Photocatalytic Degradation Using Cu-Doped Zno Nanoparticles

Abstract

Effective degrading techniques are required for environmental protection since rhodamine B (RhB) is a dye that poses a high risk of environmental pollution. ZnO is widely used in dye degradation because of its superior ultraviolet (UV) photocatalytic capability. Photocatalytic degradation technology provides a workable way to reduce such pollution. Cu-doped ZnO nanoparticles were effectively created in this work using a simple precipitation technique. The material demonstrated exceptional photocatalytic activity under UV irradiation when the Cu doping level was 0.8%; total RhB degradation was achieved in 5 hours (degradation efficiency up to 100%). The material's physical and chemical characteristics were methodically examined using transmission electron microscopy (TEM), scanning electron microscopy (SEM), and X-ray diffraction (XRD).The findings showed that while Cu insertion greatly improved ZnO's light response capabilities, it had no effect on the material's crystallinity. The photocatalytic mechanism of Cudoped ZnO was fully explored based on the experimental results of UV-catalyzed RhB solution degradation, offering theoretical insights and technological assistance for the creation of high-efficiency photocatalysts for dye degradation.
