Abstract.

Oxides of Ni-Cu were electrodeposited and characterized by SEM, IR and XPS techniques. These studies indicate that the coatings are mostly amorphous, made up of tiny particles of copper metal or a very low alloy with nickel in non-metallic phases with non-stoichiometric compositions. The deposited oxide films exhibit low overvoltages at 303 K for methanol oxidation and act as effective anode materials. Electrocatalytic activity of the deposited films depends on the composition of the coating. Under working conditions the deposits exhibit good corrosion resistance towards the electrolyte medium.
