To this end, reactive magnetron sputtering offers a simple, one-step, and relatively cost-effective technique that can be used for large-scale applications. It can achieve high deposition rates, uniform deposition over large-area substrates, and allows for easy control over the composition, oxidation states and phases of the deposited materials. However, to the best of our knowledge, reactively-sputtered copper oxide films prepared at room temperature have been rarely studied for use in supercapacitors and as electro-catalysts in the electro-oxidation of methanol.
