Water electrolysis represents one of the most environmentally friendly methods for hydrogen production, while its overall efficiency is primarily governed by the electrocatalyst. Nickel sulfides, e.g., NiS, are considered to be highly promising catalysts for the hydrogen evolution reaction (HER) due to their distinctive chemical structure. However, the practical application of NiS-based electrocatalysts is hindered by unsatisfactory high overpotential in the HER and weakened catalytic performance under alkaline conditions. Therefore, in this regard, further research on NiS-based catalysts is being carried out to tackle these challenges. This review provides a comprehensive survey of the latest advancements in NiS-based in improving the HER performance of NiS-based electrocatalysts. The review may offer some inspiration for the rational design and synthesis of novel transition metal-based catalysts with enhanced water electrolysis performance.
水电解是制氢最环保的方法之一，而其整体效率主要由电催化剂决定。硫化镍，如NiS，由于其独特的化学结构，被认为是析氢反应（HER）极具前景的催化剂。然而，基于NiS的电催化剂的实际应用受到HER中高过电位不理想以及碱性条件下催化性能减弱的阻碍。因此，在这方面，正在对基于NiS的催化剂进行进一步研究以应对这些挑战。本综述全面概述了基于NiS的催化剂在提高基于NiS的电催化剂的HER性能方面的最新进展。该综述可能为合理设计和合成具有增强水电解性能的新型过渡金属基催化剂提供一些启示。
