Abstract

Abstract Directly seawater electrolysis would be a transformative technology for large‐scale carbon‐neutral hydrogenproduction without relying on pure water. However, current seawater splitting is challenged by detrimental chlorine chemistry, the sluggish kinetics, and the existence of impurities/precipitates, making it more difficult than pure water splitting. So far, tremendous efforts have been made to develop electrocatalysts to boost the electrocatalytic hydrogen evolution reaction (HER) and oxygen evolution reaction (OER) activities for seawater‐based electrolyzers. To get further insights into the current achievements and future perspectives of the catalysts for seawater electrolysis, general principles…
