Abstract
Researchers have shown significant interest in the creation of sustainable green techniques for synthesising metal oxide nanomaterials in the past few years. Plant-mediated production is considered an affordable and feasible alternative to traditional physical and chemical approaches. This study presents a straightforward approach for the environmentally friendly production of copper oxide nanoparticles (CuO NPs) by a solution combustion technique utilising Jasminum sambac Flower Extract. The CuO NPs produced during biosynthesis were analysed using UV-Vis, XRD, FT-IR, SEM, TEM, HPLC, BET and EDX techniques. The SEM pictures reveal that the fragments possess a sponge-like structure characterised by a substantial surface area. An investigation into the photocatalytic activity of CuO NPs shows that they are effective as a catalyst for the breakdown of methylene blue (MB) when exposed to UV and solar radiation. Furthermore, the study demonstrated a pH dependence in the breakdown of MB. According to the study, the best starting concentration of dye for breaking down things completely is 2.5 parts per million (ppm), which results in a remarkable 79 % disintegration rate. The findings indicate that CuO NPs have the ability to effectively treat water by decomposing contaminants such as methylene blue, providing a sustainable method for treating wastewater.
