Hierarchical NiFe layered double hydroxides: a bifunctional electrocatalyst for overall water splitting

Electrocatalytic hydrogen production from water is limited by sluggish kinetics and requires a highly overpotential of anodic oxygen evolution reaction (OER) and cathodic hydrogen evolution reaction (HER). NiFe double hydroxides (NiFe-LDH) bifunctional group catalyst is applied to OER/HER under alkaline conditions. The good chemical contact between LDH nanosheets grown in situ (NiFe-LDH) on nickel...
