Valve metal electrode with valve metal oxide semi-conductor face and methods of carrying out electrolysis reactions

摘要

Describes chlorine resistant metal electrodes, preferably of valve metals such as titanium and tantalum, having coatings of mixed metal oxides, preferably valve metal oxides and platinum group metal oxides, which have been doped to provide semi-conducting surfaces on the electrodes, which coatings also have the capacity to catalyze chlorine discharge from the electrodes and to resist corrosive conditions in a chlorine cell and methods of electrolysis.
