In the present study, we propose a simple, one-pot mechanochemical approach to synthesize CuO nanoparticles (NPs) using the leaf extract of Seriphidium oliverianum, as a reducing and stabilizing agent. The CuO NPs were characterized via X-ray diffraction (XRD), scanning electron microscopy (SEM), photoluminescence (PL) and Fourier-transform infrared spectroscopy (FTIR). The photocatalytic activity of CuO NPs was monitored using ultraviolet-visible (UV-Vis) spectroscopy. The CuO NPs exhibited high potential for the degradation of water-soluble industrial dyes. The degradation rates for methyl green (MG) and methyl orange (MO) were 65.231% ± 0.242 and 65.078% ± 0.392, respectively. Bio-mechanochemically synthesized CuO NPs proved to be good candidates for efficiently removing dyes from water184028178engphotocatalysisdegradationcopper oxidenanoparticlesmethyl greenmethyl orangedyeswastewaterbiomimeticenvironmentally benignphotochemicalpurificationwaste managementSDG 6 - Clean Water and SanitationSDG 12 - Responsible Consumption and Productionjournal article10.3390/catal13030502https://www.scopus.com/pages/publications/85152058661
