摘 要: 氢能作为一种清洁、高能、无二次污染的“绿色能源”，被认为是后石油时代解决能源危机和环境危机的理想能源之一。其中电解水析氢技术因反应高效、易控、无污染等特点而逐渐成为研究热点。目前析氢性能最好的催化剂依然是Pt基催化剂。然而Pt储量少、价格贵，无法满足大规模氢气生产的现实需求。因此，如何进一步提高现有非Pt催化剂的析氢性能或开发廉价高效的新型催化剂是实现电解水析氢规模化生产的关键。结合本课题组在电解水方面的研究工作，综述近几年非Pt析氢催化剂的研究新进展，重点介绍新型过渡金属化合物催化材料的结构设计与调控对析氢性能的影响，并对电解水析氢催化剂面临的挑战及发展方向进行展望。

Abstract:Hydrogen energy is a clean, high energy, environmentally friendly resource which is considered as one of the most promising candidates for replacing fossil fuels in the future. Electrochemically splitting water into hydrogen by renewable energy has attracted much attention due to its high efficiency, easy operation and no secondary pollution. Although the state-of-the-art catalyst for HER is a typical Pt-based catalyst, its scarcity and high cost prevent their widespread applications. Thus, it is highly desirable to exploit non-Pt HER catalysts with high activity, long-term stability and low cost. The recent advancements in the area of non-Pt HER catalysts with emphasis on introducing the exciting new research in the structure regulation of transition metal compounds and the understanding of the mechanisms of catalysts were reviewed. Meanwhile, the insights into the remaining challenges and research directions were proposed to shed light on future development of non-Pt HER catalysts.
