Abstract

Cathode, working with an alkaline medium, has >=1 surface made of a compsn. comprising (a) Ni, Co, Fe, Cu or Zn and (b) Ni, Co, Fe, Cu, Zn, ti, Mo, W, Mg, Mn, Nb, V, Ta,B, the rare earth metals and their hydrides. Esp. used for electrolysis of alkali chlorides. The cathode exhibits reduced overvoltage without prohibitive extra production and operating costs being needed. Pref. the surface comprises a binary cpd. formed between metals of the two gps. Alternatively the cathode has >=1 surface coated with a non-stoichiometric compsn. of formula AxByO2 of tungsten bronze type, where x = 0-1. Pref. A is Na and the B is selected from the second group of metals above and is esp Ti. Na ratio is 2-2.5. The compsn. is mixed the metallic cpd. in amount such that the ratio of the metal of the first group above to the non-stoichiometric cpd.
