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 (RuO2/TiO2/SnO2) 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.
