电催化裂解制氢是减少碳排放和生产可再生燃料的一种有吸引力的方法。然而，这一前景看好的工艺受到反应动力学缓慢和昂贵催化剂的限制。构建低成本、高性能的非贵金属基催化剂是应对这些重大挑战的最有效途径之一。值得注意的是，电子结构调整策略可以微妙地调整催化剂的电子态、能带结构和吸附能力，已成为进一步提高基于非贵金属催化剂的电化学水分解反应的关键途径。特别是，杂原子掺杂在调节催化剂的电子结构和优化催化剂的本征活性方面起到了有效的作用。然而，反应动力学，特别是催化剂中杂化物质的作用机理仍不明确。本文综述了近年来杂原子掺杂的非贵金属基析氢催化剂的研究进展，重点介绍了催化剂中杂原子的电子调谐效应以及相应的合成途径、催化性能和活性来源。本综述还试图建立局域电子结构与催化性能之间的内在联系，为开发先进的低成本催化剂提供很好的参考。
Electrocatalytic water splitting for hydrogen production is an appealing way to reduce carbon emissions and generate renewable fuels. This promising process, however, is limited by its sluggish reaction kinetics and high-cost catalysts. Construction of low-cost and high-performance non-noble metal-based catalysts have been one of the most effective approaches to address these grand challenges. Notably, the electronic structure tuning strategy, which could subtly tailor the electronic states, band structures, and adsorption ability of the catalysts, has become a pivotal way to further enhance the electrochemical water splitting reactions based on non-noble metal-based catalysts. Particularly, heteroatom-doping plays an effective role in regulating the electronic structure and optimizing the intrinsic activity of the catalysts. Nevertheless, the reaction kinetics, and in particular, the functional mechanisms of the hetero-dopants in catalysts yet remains ambiguous. Herein, the recent progress is comprehensively reviewed in heteroatom doped non-noble metal-based electrocatalysts for hydrogen evolution reaction, particularly focus on the electronic tuning effect of hetero-dopants in the catalysts and the corresponding synthetic pathway, catalytic performance, and activity origin. This review also attempts to establish an intrinsic correlation between the localized electronic structures and the catalytic properties, so as to provide a good reference for developing advanced low-cost catalysts.
