Abstract:

The demand for energy is increasing as the society develops rapidly. Hydrogen production from water electrolysis has become a research hotspot for its prominent advantages. Rational design of water electrolysis catalysts with strong stability and high selectivity is one of the key issues of this study. The Pt group elements are a class of noble metal elements with the highest electrocatalytic activity, which makes them the ideal choice for the catalysts of hydrogen evolution reaction (HER). But their high price hinders the scale development. Single atom catalysts (SACs) can effectively reduce the loading of noble metal elements and improve their atomic utilization rate. Thus, SACs can greatly reduce the catalyst cost and facilitate the large-scale industrial application of precious metal catalysts. The status quo of catalysts for hydrogen production from water electrolysis are systematically reviewed, especially the Pt-based SACs, in view of their unique importance in chemical industry. The development of SACs is prospected, which provides a reference for researchers advancing hydrogen production from water electrolysis technology and its industrial applications.

Key words: water electrolysis for hydrogen production, single atom catalyst, atom utilization efficiency, precious metal catalyst, hydrogen evolution reaction
