The production of chlorine by electrochemical oxidation of chlorides (chlor–alkali technology, CAT) is nowadays one of the largest processes in industrial electrochemistry. The main products – chlorine and the corresponding hydroxide – are, besides sulfuric acid and ammonia, the most important industrial inorganic chemicals. The third product – hydrogen (as a by-product) – is very valuable from the standpoints of contemporary power sources (“hydrogen economy;” fuel cells) and different industrial synthesis (mostly organic). the tailoring of the synthesis of electrode materials at the nanolevel, in order to increase the catalyst efficiency and/or to reduce the catalyst consumption, is seen as a valuable future direction in the development of advanced materials in chlorine electrocatalysis.
