Effect of Cations of Alkali and Alkaline-Earth Metal Chlorides for Chlorine Evolution Reaction

The chlorine evolution reaction was conducted on a metal-oxide-coated titanium anode (RuO 2 /TiO 2 /SnO 2 ) in neutral chloride solutions of sodium, magnesium, strontium, and barium, using steady-state E −(log i ) curves. From the results, it is concluded that the chlorine evolution reaction has no dependence on the cations in alkali and alkaline-earth metal chlorides.
