Abstract:
     A highly durable, stable electrode having a coating comprised of an oxide of at least one metal selected from nickel and cobalt, which coating additionally contains titanium and zirconium components in proportions of 0.1 to 3.5% in terms of atomic percentage of titanium and 0.1 to 3% in terms of atomic percentage of zirconium, respectively. The electrode can advantageously be used in electrolyses in which hydrogen is evolved on the electrode, such as electrolyses of an alkali metal chloride and water. The electrode advantageously exhibits a low hydrogen overvoltage, enabling electrolysis to be performed stably for a prolonged period of time.
