Developing sustainable energy sources is crucial to combat energy shortages and reduce carbon emissions. Green hydrogen production through water electrolysis using renewable energy is gaining traction. Anion exchange membrane water electrolysis (AEMWE) has emerged as a promising technology for sustainable development. The article discusses the significance of AEM-based seawater electrolysis (AEMSE) due to the abundance of seawater as a feedstock. However, challenges persist in developing stable electrocatalysts for seawater electrolysis due to Cl- interference and electrode deterioration. Transition-metal materials (TMMs), such as Ti3C2, show potential in enhancing OER performance in seawater electrolysis. By employing Ti3C2 to assist NiFe sulfides catalyst ((Ni,Fe)S2@Ti3C2), the article demonstrates improved OER activity and stability. The strong interaction between Ti3C2 and (Ni,Fe)S2 prevents metal dissolution and enhances Cl- resistance. The catalyst achieves high OER activity and long-term durability in seawater, showcasing its practicality for industrial applications. The study highlights the importance of developing efficient and stable electrocatalysts for AEMSE to enable the large-scale production of green hydrogen.
