NiSe/Ni3Se2 on nickel foam as an ultra-high-rate HER electrocatalyst: common anion heterostructure with built-in electric field and efficient interfacial charge transfer

The NiSe/Ni 3 Se 2 common anion heterostructure is a superior electrocatalyst for ultra-high-rate HER owing to its built-in electric field and efficient interfacial charge transfer.
