Built-in electric field control of electron redistribution (NiFe-based electrocatalyst) with efficient overall water splitting at industrial temperature

Nickel-iron layered double hydroxide (NiFe-LDH) is hindered in its further development in water splitting due to its slow kinetics of oxygen evolution reaction (OER) and hydrogen evolution reaction (HER). In this study, the synthesis of OER (FeO(OH)/NiFe-LDH) and HER (Fe
