methanol oxidation activity of cuo nanoparticles obtained from thermal decomposition of copper-salophen complex

Today, fuel cells (fcs) are considered as one of the tools to achieve the basic goal of the future of human society [1, 2]. in this context, the design of metal oxide nanomaterials as electrochemical catalysts has attracted much attention [3]. here, we investigate the electrocatalytic activity of copper oxide nanoparticles obtained from the thermal decomposition of cu-salophen complex for methanol oxidation. to monitor the efficiency of this material in methanol oxidation reaction, cyclic voltammetry technique was used in 1m koh solution, which showed a peak current density of ~247.51 ma cm-2 in 0.5 m methanol concentration. also, the durability of the electrode was investigated using the chronoamperometry technique, which showed long-term stability. in addition, from the impedance analysis, a charge transfer resistance of 11.22 ω cm-2 was obtained, indicating a faster electron transfer process at the interface. the results of this study confirm the fact that cuo nanostructures obtained from the thermal decomposition of cu salophen complex is a promising electrocatalyst for methanol oxidation.
