Seawater electrolysis offers a promising pathway to generate green hydrogen, which is crucial for the net-zero emission targets. Indirect seawater electrolysis is severely limited by high energy demands and system complexity, while the direct seawater electrolysis bypasses pre-treatment, offering a simpler and more cost-effective solution. However, the chlorine evolution reaction and impurities in the seawater lead to severe corrosion and hinder electrolysis's efficiency. Herein, we review recent advances in the rational design of chlorine-suppressive catalysts and integrated electrolysis systems architectures for chloride-induced corrosion, with simultaneous enhancement of Faradaic efficiency and reduction of electrolysis's cost. Furthermore, promising directions are proposed for durable and efficient seawater electrolysis systems. This review provides perspectives for seawater electrolysis toward sustainable energy conversion and environmental protection.
海水电解为生产绿色氢气提供了一条有前景的途径，这对于实现净零排放目标至关重要。间接海水电解受到高能量需求和系统复杂性的严重限制，而直接海水电解绕过了预处理，提供了一种更简单且更具成本效益的解决方案。然而，析氯反应和海水中的杂质会导致严重腐蚀，并阻碍电解效率。在此，我们综述了用于抑制氯化物诱导腐蚀的氯抑制催化剂和集成电解系统架构的合理设计方面的最新进展，同时提高法拉第效率并降低电解成本。此外，还为耐用且高效的海水电解系统提出了有前景的方向。本综述为海水电解实现可持续能源转换和环境保护提供了观点。
