This study details the synthesis, characterization, and photocatalytic efficacy of zinc oxide (ZnO) nanoparticles (NPs) obtained through an environmentally friendly method with varying quantities of Rubus glaucus as a chelating agent. Examination of X-ray Diffraction (XRD) and Transmission Electron Microscopy (TEM) data unveiled ZnO NPs featuring a wurtzite structure and sizes ranging from 43.39 to 28.01 nm. The analysis indicated that the presence of Rubus glaucus extract during synthesis influenced the size and band gap of the ZnO NPs, resulting in a decrease from 2.8 to 2.5 eV. The photocatalytic performance of ZnO NPs was assessed through the degradation of synthetic dyes methylene blue (MB), methyl orange (MO), and rhodamine B (RhB). The results demonstrated enhanced photocatalytic activity for the ZnO NPs, with ZnO-RG3 exhibiting the most effective degradation. Under UV light, ZnO-RG3 degraded 99%, 95%, and 95% of MB, MO, and RhB within 90 min, while under sunlight, it achieved degradation rates of 98%, 85%, and 95% for MB, MO, and RhB within the same timeframe. These findings underscore the effectiveness of Rubus glaucus extract as a chelating agent in producing metal oxide nanoparticles with remarkable photocatalytic performance under both UV and sunlight conditions.
