摘　　要：It is of great importance to design and develop electrocatalysts that are both long-lasting and efficient for seawater oxidation.Herein,a three-dimensional porous cauliflower-like Ni_(3)S_(2) foam on Ni foam(Ni_(3)S_(2) foam/NF)is proposed as a high-performance electrocatalyst for the oxygen evolution reaction in alkaline seawater.The as-synthesis Ni_(3)S_(2) foam/NF achieves exceptional efficacy,achieving a current density of 100 mA·cm^(−2)at mere overpotential of 369 mV.Notably,its electrocatalytic stability extends up to 1000 h at 500 mA·cm^(−2).
