| Summary: | This study highlights the synthesis and characterization of copper oxide/reduced graphene oxide (CuO/rGO). Copper oxide (CuO) was synthesized using a solution combustion method, employing Ashwagandha plant (Withania somnifera) as a biofuel. The CuO/rGO nanocomposite was then prepared via a straightforward reflux method. Comprehensive structural, functional, and morphological analyses were conducted using XRD, UV–Vis, HR-SEM, EDAX and FTIR techniques. The photodegradation of CuO/rGO was demonstrated by degrading Rose Bengal dye (RB) at a concentration of 10 ppm within 120 min, follows 1st-order kinetics with a high degradation rate of 95.70 %. The catalyst's half-life was calculated as 26.82 min, underscoring its efficient photocatalytic performance. Additionally, reusability tests confirmed the catalyst's stability over six cycles, maintaining consistent catalytic efficiency. This work is the first to report the degradation of RB dye using a CuO/rGO composite. |
