Green synthesis of copper oxide nanoparticles (cuo nps) using orange (citrus sinensis) peel extract and their photocatalytic performance on rose bengal b dye

Copper oxide nanoparticles (CuO NPs) are synthesized through green synthesis, utilizing the natural phytochemicals present in orange (Citrus sinensis) peel as green stabilizing and reducing agents. This synthesis route offers several advantages, including higher sustainability, eco-friendliness, low...
