Abstract: Seawater electrolysis, for hydrogen production has attracted more and more attention. Therefore,
it is of great significance to design and develop efficient and stable catalysts for hydrogen production
through natural seawater (or brine electrolyte) electrolysis. Herein, the status quo of seawater electrolysis
was firstly analyzed. Then, the design ideas and modification methods of electrocatalysts for seawater
electrolysis were summarized, followed by review on the latest research progress in the synthesis of
efficient and stable catalysts for seawater electrolysis via construction of special structure, such as
three-dimensional layered porous nano structure, protective layer structure and surface wettability structure.
Finally, the existing challenges and development directions were summarized and prospected. It was
suggested that, in the future research, combination of experimental and theoretical research as well as
characterization technique, was needed to develop more efficient, stable and highly selective catalysts so as
to meet the requirements of the industrial application of seawater electrolysis.
Key words: electrolysis; seawater; hydrogen evolution; oxygen evolution; catalysts
