Abstract:

The huge importance of sustainable energy makes the research of the green and environmental hydrogen energy active in the world. Energy conversion and storage technologies (such as fuel cells or water electrolysis) are capable of readily promoting the interconversion between hydrogen and electric power, for which the development of efficient and stable electrocatalysts is prerequisite. Ordered intermetallic compounds are considered as superior electrocatalysts for energy conversion storage technologies and ideal models for studying the relationship between catalytic activity and structure due to uniform distribution of active sites on surface, well-defined stoichiometry and the better control of the local geometry and electronic structure of metal atoms, compared to disordered alloys as their counterparts. In this review, the challenges of catalysts with regard to hydrogen-electric conversion and the advantages of intermetallic compounds in electrocatalysis are firstly introduced. Secondly, research progress on intermetallic compounds electrocatalysts applied in the interconversion between hydrogen and electric power is mainly discussed from the perspective of activity and stability. Finally, the future development prospects of intermetallic electrocatalysts are summarized and prospected.

Key words: Interconversion between hydrogen and electric power, Intermetallic compounds, Electrocatalysis
