摘　　要：Water splitting is recognized as an environmentally friendly and feasible method to produce hydrogen.However, the high cost, low storage capacity, and poorstability of traditional noble metal-based electrocatalysts haveseverely limited the industrial application of electrocatalyticwater splitting. The utilization of seawater splitting not onlyfacilitates the production of high-purity hydrogen on a largescale but also concurrently promotes the desalination process.Over the past decades, transition metal borides (TMBs) havebeen widely used in the field of water splitting due to theadvantages of simple preparation process, good stability, andeasily adjustable composition. This review summarizes therecent progress of TMBs in the electrolysis of water and seawater.Firstly, the influencing factors of electrocatalytic performance and related evaluations are introduced. The basicprinciples of hydrogen evolution reaction, oxygen evolutionreaction, and chlorine evolution reaction in seawater electrolysisare discussed in detail, pointing out the various problemscaused by chloride ions (Cl^(−)) in the process of hydrogenproduction from seawater splitting. In addition, the preparation and optimization strategies of TMBs are emphasized.Finally, the development, challenges, and prospects of electrolytic seawater hydrogen production technology are presented. This review aims to furnish deeper insights intoenhancing the electrocatalytic performance of TMBs in thiscritical area of research.电解水被认为是一种环保、可行的氢能生产方法.然而,传统的贵金属基电催化剂成本高、储存能力低、稳定性差,严重限制了电催化水分解的工业应用.利用电解海水不仅有助于大规模生产高纯度氢气,还能同时促进海水淡化过程.在过去的几十年中,过渡金属硼化物(TMBs)因其制备工艺简单、稳定性好、成分易于调节等优点,在海水裂解领域得到了广泛的应用.本综述总结了过渡金属硼化物在电解水和海水方面的最新进展.首先,介绍了电催化性能的影响因素及相关评价.详细讨论了海水电解中析氢反应、析氧反应和析氯反应的基本原理,指出了电解海水制氢过程中氯离子(Cl^(-))引起的各种问题.此外,还强调了TMBs的制备和优化策略.最后,介绍了电解海水制氢技术的发展、挑战和前景.本综述旨在为在这一关键研究领域提高TMBs的性能提供更深入的见解.
