Abstract
The yield of metal hydroxides obtained by electrolysis of chloride baths is greater than the yield obtained from nitrate baths showing that the hydrogen evolution reaction (HER) contributes as much to electrogeneration of base as the nitrate reduction reaction. This observation has implications for the fabrication of nickel hydroxide positive electrodes for alkaline secondary cells, and widens the scope of electrosynthesis to include chloride, sulphate and other anion containing α-nickel hydroxides and other layered hydroxides. Electrosynthesis of Mg(OH)2 has been investigated as a model synthesis.
