Herein, a green synthesis methodology for making copper oxide (CuO) nano particle cluster in a cost effective and a simple way is reported. While cuprous sulfate pentahydrate is used as a source of copper, the outer layer of green peas (Pisum Sativum) is used as a source of phenol. Extracting the phenol from pea peels is a simple process that uses water as a solvent. Copper salt is reduced by the phenolic content that is so produced. Both physico-chemical and microscopic characterization Scanning Electron Microscope (SEM), Energy-dispersive X-ray (EDX) analysis (EDAX) were performed on the particles. A variety of pea peeling samples were used during the procedure' several executions to ensure reproducibility. The preparation process was appropriate, as the outcomes were identical. Analyses were also conducted on the produced particles' electro-chemical activity as an application. A well-defined and organized redox reaction was seen at E' = +0.25 V against Ag/AgCl which were also shown to be highly electro-active in nature. With the benchmarked redox mediator (5 mM ferricyanide), the particles also produced an outstanding redox peak at E1/2= -0.01 V vs. Ag/AgCl. In a common reducing organic reaction, such as the reduction of p-nitro phenol to p-amino phenol, they were also found to be an effective catalysts. Additionally, tests were conducted on the produced particles' for there anti-bacterial and antifungal properties. Overall, a simple method for formation of commercially viable CuO nano particle cluster is developed with a potential of diverse applications.
