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.
