Background
Electrochemical water splitting is an efficient, safe, and long-term method of producing hydrogen, which is one of the most appealing renewable fuels. To avoid the harmful effects of acid fog and to keep electrolyzers from corroding, alkaline water electrolysis has been frequently used. However, because of the low efficiency of water dissociation, the catalytic activity of the HER in an alkaline medium is substantially weaker than in an acidic medium. The…
