Green synthesis of nanocomposites: AgO, CuO and Ag/CuO NPs from extracts of the bulb of UrgineaMaritima and their application for the degradation of the dye Cristal Violet

The search for an economically viable and environmentally benign method for the treatment of wastewater represents a significant global challenge. Accordingly, this study examined the removal of organic pollutants from wastewater through the use of copper oxide, silver oxide, and silver-doped copper oxide nanoparticles, which were synthesized from the extracts of the plant Urginea maritima. The green synthesis of nanoparticles represents a simple, rapid, cost-effective and environmentally friendly method that has demonstrated efficacy in the removal of organic dyes from wastewater. The characterization of these nanoparticles by XRD and UV-Visible spectroscopy demonstrates the formation of copper and silver oxides in the different syntheses. The results of the degradation of crystal violet indicate that silver-doped CuO exhibits a higher photodegradation efficiency than undoped CuO in the different syntheses, with an efficiency of 98.22% after a time of 60 minutes. This makes them a highly promising catalyst for water purification and environmental remediation.
