Alkaline water splitting for hydrogen production broadens the selection of the electrocatalysts to non-noble metal or metal oxides, but has more sluggish kinetics than acidic water splitting. To address this, the researchers have developed a number of atomically dispersed electrocatalysts based on earth abundant metals, which was coined as single-atom-catalysts (SACs). SACs exhibit high activity for hydrogen evolution reaction (HER), due to the high atom utilization, high activity, and high selectivity. In this talk, I will review various preparations of SACs on carbon, and discuss the electrocatalytic performance for alkaline HER. Emphasis will be on how to increase the metal atom loading for industrial applications.
