Constructing a dual-protection heterointerface for durable anion exchange membrane seawater electrolysis at ampere-level current density.

ABSTRACT: Chloride ions (Cl^-) pose a corrosive challenge to the long-term durability of metal catalysts during seawater electrolysis for sustainable hydrogen production. The construction of heterointerfaces has been demonstrated to enhance the corrosion resistance of highly active transition metals by preventing direct contact with Cl^- in seawater. However, reliance on a single protection mechanism has hindered further advances in heterojunction catalysts. In particular, the charge-transfer regulation induced by the spatial electric field at heterointerfaces has often been overlooked. Herein, we investigate the Cl^- corrosion behavior at the graphene/NiMo interface, which serves as a hydrogen evolution catalyst for durable seawater electrolysis. The spatial electric f
