This study presents a novel approach to address synthetic dye pollution in wastewater by introducing a novel ZnO/CuO/Cu
2 MgO3 nanocomposite (NC) synthesized using a green method involving Common Rue plant extract. Through a series of meticulous experimental procedures, the synthesized materials exhibited remarkable properties. The ZnO/CuO/Cu2 MgO3 NC exhibits a moderate band gap energy of 1.5 eV, confirming its semiconductor nature. XRD analysis revealed crystallite sizes of 29 nm. FTIR analysis provided insights into chemical compositions. SEM reveals well-defined, spherical nanocomposite particles. The research aims to investigate the photocatalytic degradation efficiency of this nanocomposite, with a focus on removing Bromocresol Green (BCG), a recalcitrant synthetic dye in wastewater. Photocatalytic degradation experiments demonstrate an impressive 99.66% BCG removal efficiency through adsorption within 75 min of solar irradiation with a rate constant of 0.091 min−1 . The nanocomposites exhibited excellent recyclability, maintaining their photocatalytic activity over five consecutive cycles. This study introduces an eco-friendly nanocomposite and synthesis approach, offering a rapid and efficient solution for BCG degradation and addressing the challenges posed by synthetic dye pollutants in wastewater.
