Abstract
Seawater electrolysis is one most promising development directions for future hydrogen energy.How-ever,big challenges of active site poisoning,chloride oxidation(ClOR),and chloride corrosion on anode electrocatalysts,seriously impede seawater electrolysis development.Therefore,developing efficient an-odic oxygen evolution reaction(OER)electrocatalysts is an urgent task for seawater electrolysis.The ad-vanced strategies of improving OER kinetics,lowering ClOR kinetics,strengthening corrosion resistance,and recombining multifunction are summarized and analyzed to help researchers quickly grasp the re-cent progress on seawater oxidation.The outlooks for future research are put forward.The future research directions are proposed as internal and external cultivation,giving full play to the physicochemical prop-erties of electrocatalysts,making sense of structure evolution and OER mechanism,and elucidating the electrical double layer of electrocatalysts.A lot of room for scalable application of seawater electrolysis calls for persistent effort and devotion of related researchers to boost seawater electrolysis development and universal hydrogen energy application.
