Abstract There is practical interest in the use of titanium as a cathode material in brine electrolysis processes. The overvoltage of hydrogen evolution on titanium is, however, very high and, at the same time, hydrogen penetrates the bulk of the metal. Here, a new type of catalytically active coating has been applied on the surface of titanium in order to overcome these problems. The coating consists of a mixture of the thermal decomposition products of lanthanum chloride and sodium molybdate. The coating has been tested for 18 months of continuous operation. No change in the overvoltage gain (of 0.4 V at 3 kA m−2, as compared with pure titanium) nor change in the properties of the bulk metal have been noticed during this period.
