Hierarchical hetero-Ni 3 Se 4 @NiFe LDH micro/nanosheets as efficient bifunctional electrocatalysts with superior stability for overall water splitting

Hierarchical hetero-Ni 3 Se 4 @NiFe LDH micro/nanosheets were prepared by coupling NiFe LDH nanosheets with Ni 3 Se 4 micro-sized sheets, and could be used as bifunctional electrocatalysts with excellent activity and durability for overall water splitting.
