Hierarchical FeCo LDH/NiSe heterostructure electrocatalysts with rich heterointerfaces for robust water splitting at industrial-level current density

A hierarchical FeCo LDH/NiSe@NF nanowire–nanosheet heterostructure was fabricated via a two-step hydrothermal–electrodeposition strategy with excellent large-current-density OER activity and long-term stability.
