The article discusses the potential of seawater electrolysis as a green energy technology for efficient hydrogen production. It highlights the challenges faced in the process, such as cathode stability issues and anode corrosion, and proposes innovative solutions to overcome these challenges. Strategies like self-cleaning cathodes, precipitate removal, and anti-corrosion treatments are suggested to enhance the stability of electrodes in seawater. The importance of regulating the electrode surface microenvironment and creating unique coordination environments for active atoms is emphasized to improve the performance of seawater electrolysis. Contrary to the traditional belief that chloride ions accelerate anode corrosion, certain catalysts can benefit from the unique coordination environment provided by chloride ions, potentially enhancing the oxygen evolution reaction (OER) performance. The article also discusses the latest advancements in industrializing seawater electrolysis, including techniques like in situ electrolysis of undiluted seawater and the use of three-chamber dual anion membranes with circulating electrolyte systems. Successful implementation of seawater electrolysis not only alleviates pressure on freshwater resources but also offers a sustainable source of clean energy for global development.
