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

A promising electrocatalyst with an amorphous-crystalline structure was designed through a NaBH 4 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. A durable and efficient surface-boron-rich electrocatalyst for seawater splitting was designed through a NaBH 4 reduction strategy.
