This research provides valuable insights into the application of ZnO nanoparticles in photocatalytic wastewater treatment. Process optimization was carried out by determining ratio surface area to energy band gap (S/E) photocatalysis rate under different sources light (UV light, visible sunlight). The were synthesized using precipitation technique, and calcination process within a temperature range 400 700 °C. structural, morphological, optical properties materials investigated X-ray powder diffraction (XRD), scanning electron microscopy (SEM), UV-Vis diffuse reflectance (UV-Vis DRS), Raman spectroscopies, Fourier transform infrared (FTIR) spectroscopies. study demonstrates that significantly influences activity altering their size, properties, shape, behavior. Optimal decomposition efficiencies Rhodamine B achieved at °C, with yields 24%, 92%, 91% visible, UV, sunlight irradiation, respectively.

Introduction: Enhancing the photoelectrochemical response of TiO2 nanotube arrays (TNA) is crucial to improve efficiency solar energy utilization. In this work, TNA was prepared electrochemically by anodization at single voltages 20 V, 30 V and 40 as well a special two-step voltage V-20 V-40 respectively. X-ray diffraction (XRD) scanning electron microscopy (SEM) were used characterize morphology crystalline structure sample. Methods: The measured electrochemical potentiostatic technique. results show evenly aligns with increasing voltage. Results: However, there that does not form dispersed fragments on surface higher voltage, which adversely affects TNA’s properties. Conclusion: During process anodization, oxidation current changes due switch in A method enhances pure TNA's visible light.
