摘要:

人类对可持续能源的高度重视,使得绿色环保的氢能成为研究热点。能量转换和存储技术(如燃料电池和电解水)可实现氢能源和电力的相互转换,但实现这些技术的前提是需要开发高效稳定的催化剂。结构有序的金属间化合物具有确定的组成和可调控的几何效应和电子效应的优势,已被探索作为能量转换和存储技术的有效电催化剂,金属间化合物表面均匀的活性位点分布也有利于研究催化剂活性和结构之间联系(即构效关系)的理想模型。本综述首先介绍了氢电转换装置催化剂所面临的挑战以及金属间化合物在电催化中的优势,其次从活性和稳定性的角度重点论述金属间化合物在氢电转换装置中的研究进展,最后总结并展望了金属间化合物电催化剂未来的发展前景。

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
