The development of earth-abundant electrocatalysts for hydrogen production from low-grade and saline water with renewable electricity is highly desired but very challenging due to the interference of side reactions and various impurities. Yuan et al. give a conceptual understanding of direct seawater splitting with the difference to the electrolysis in pure water. Effective strategies for the rational construction of electrocatalysts with improved selectivity and stability on both anode and cathode based on possible electrochemistry involved in this process are discussed, including thermodynamically restricting chloride chemistry, designing selective active species and constructing protecting layers. Rational design of highly efficient and stable electrolysers is also required for the implement of direct seawater electrolysis. For the guidelines of future research, recent achievements are discussed and issues to be solved are provided.
