Combination of reactive magnetron sputtering of cobalt particles in oxidation Ar+O2 atmosphere and electrochemical formation of cobalt hydroxide precursors using cathodic reduction of cobalt nitrate in aqueous solution was applied for coating of the supports the precursors were then transformed to Co3O4 by subsequent heating at 500 °C in air. Two plasma enhanced PVD methods, namely the radio-frequency (RF) magnetron sputtering and high-power impulse magnetron sputtering (HiPIMS) were used for obtaining of Co3O4 thin films. The catalysts prepared using RF magnetron sputtering were more active than analogous catalysts prepared using the HiPIMS process. The catalyst obtained by electrochemical deposition on a bare stainless steel mesh had the highest Co3O4 loading and showed the highest efficiency in total ethanol oxidation.
