A boronization-induced amorphous–crystalline interface on a Prussian blue analogue for efficient and stable seawater splitting

Abstract

A promising electrocatalyst with an amorphous–crystalline structure was designed through a NaBH₄ reduction strategy. Such a surface-defective heterophase structure remarkably prevents the catalyst from corroding by hindering the transport of Cl⁻, resulting in efficient and stable overall seawater splitting.
