Abstract :
In this work, CuO nanoparticles (CuO NPs) was prepared by a simple and green method using Rosmarinus officinalis extract containing phenolic constituents as both the chelating and the stabilizing agents. CuO nanoparticles/polyorthoaminophenol composite (CuO NPs/POAP) as electro-active electrodes for electrocatalytic oxidation of methanol with good uniformity are prepared by electropolymerization. Composite of CuO NPs/POAP was synthesized by cyclic voltammetry (CV) methods and electrochemical properties of film were investigated by using electrochemical techniques. New composite modified electrode shows a significantly high response for methanol oxidation. This method of synthesis of the catalyst and composite has the advantages of high yields, elimination of chemical reagent and simple methodology. Catalytic efficiency remains unaltered even after several repeated cycles.
