摘要： This invention relates to a method of producing metal electrodes by treating a metal electrode substrate so as to coat the substrate surface with a homogeneous solution of the compounds of (i) at least one metal selected from a first group of iron, cobalt, nickel and manganese (ii) at least one other metal selected from a second group of molybdenum, tungsten and vanadium, each of which compound is capable of thermal decomposition to the corresponding metal oxide. The coated substrate is then thermally decomposed and the oxide-coated substrate is cured in a reducing atmosphere at elevated temperature. Substrates coated with Ni-Mo oxides are preferred. The electrodes thus produced exhibit very low overvoltage, are of high stability with respect to their activity and can be used as cathodes for the electrolysis of water or brine.
