| Abstract Scope |
Promoting environmentally friendly materials is increasingly critical across all engineering fields. This study focuses on sustainable composite materials, emphasizing natural sourcing, raw material recycling, and lifecycle enhancement to minimize waste. Specifically, it explores the kinetic photodegradation of Rhodamine B dye using (Ni-ZnO)prepared via spray pyrolysis. The composite exhibits enhanced photocatalytic activity for degrading organic pollutants under UV and solarlight, achieved through nickel ion incorporation into the zinc oxide. Characterization techniques like X-ray diffraction confirmed the formation of hexagonal ZnO and Ni-ZnO films, with SEM and TEM revealing a dense structure of spherical-shaped crystals due to nickel doping. UV-Vis spectroscopy highlighted varying optical properties, crucial for understanding photocatalytic efficiency. Results demonstrated the material's capability under UV and solar irradiation, optimizing catalyst concentration, pH, and light source for efficient dye degradation. This research underscores Ni-ZnO composites potential in sustainable manufacturing, offering insights into eco-friendly materials for environmental applications, particularly in wastewater treatment. |
