Abstract

Electrocatalytic water splitting as a green chemical process to evolve H2 has increasingly attracted attention. Using fresh water as the proton source not only increases the cost but also significantly hinders the wide applications of electrocatalysis in H2 production. Instead, seawater is more competitive compared to fresh water from the economic aspects, but more challenging from the technical aspects. Technically, insoluble solids and chloride ions in seawater significantly affect the electrocatalytic activity and stability of catalysts. Great efforts have been spared to develop highly effective electrocatalysts for seawater splitting, and various strategies have been raised. Herein, we categorized and discussed recently reported composites applied in electrocatalytic seawater splitting. Future perspectives for the advancement of seawater-based electrocatalysts have been proposed at the end. We hope to provide some new understanding and methods for the reasonable construction of state-of-the-art electrocatalysts to tackle the challenges of seawater splitting.

摘要

电催化水裂解作为一种绿色的制氢过程受到人们的关注。使用淡水作为电解液不仅增加了成本, 而且严重阻碍了电催化在制氢中的广泛应用。相反, 海水在经济方面比淡水更有竞争力, 但在技术方面更具挑战性。从技术上讲, 海水中的不溶性固体和氯离子会严重影响催化剂的电催化活性和稳定性。目前, 人们一直在努力开发高效的海水裂解电催化剂, 并提出了各种策略。在此, 我们对最近报道的用于电催化海水裂解的复合材料进行了分类和讨论。最后, 对海水基电催化剂的发展前景进行了展望。我们希望可以为合理构建最先进的电催化剂以应对海水分解的挑战提供一些新的认识和方法。
