Nickel-Copper Oxide Catalysts Deposited on Stainless Steel Meshes by Plasma Jet Sputtering: Comparison with Granular Analogues and Synergistic Effect in VOC Oxidation

A novel method for the preparation of Ni-Cu oxide catalysts—deposition on stainless steel meshes using hollow cathode plasma jet sputtering—was studied. This allows thin films. Consequently, whole volume active phase is readily accessible reactants and can be employed in catalytic reaction due to negligible effect internal diffusion. As a result, activity our sputtered catalyst was seven times higher ethanol oxidation 61 toluene than that corresponding granular catalyst. Moreover, used as support, pressure drop across bed lower. Finally, with Ni:Cu molar ratio 1:1 1.7 commercial EnviCat® VOC-1544 catalyst, while amount 139 The outstanding performance Ni0.5Cu0.5 ascribed synergistic between copper nickel components.
