MXene-Assisted NiFe sulfides for high-performance anion exchange membrane seawater electrolysis.

ABSTRACT: Anion exchange membrane seawater electrolysis is vital for future large-scale green hydrogen production, however enduring a huge challenge that lacks high-stable oxygen evolution reaction electrocatalysts. Herein, we report a robust OER electrocatalyst for AEMSE by integrating MXene (Ti₃C₂) with NiFe sulfides ((Ni,Fe)S₂@Ti₃C₂). The strong interaction between (Ni,Fe)S₂ and Ti₃C₂ induces electron distribution to trigger lattice oxygen mechanism, improving the intrinsic activity, and particularly prohibits the dissolution of Fe species during OER process via the Ti-O-Fe bonding effectively, achieving notable stability. Furthermore, the good retention of sulfates and the abundant groups of Ti₃C
