摘要：

Seawater electrolysis for green hydrogen production is one of the key technologies for achieving carbon neutrality. However, in anode systems, the chloride ions (Cl−) in seawater will trigger an undesired chlorine evolution reaction (CER) that competes with an oxygen evolution reaction (OER), resulting in inferior OER activity and selectivity. Besides, the corrosive Cl− and its derivative products will corrode anodes during seawater electrolysis, leading to poor stability. Therefore, great efforts have been devoted to developing efficient str...
