Dynamic Adsorption of Molybdate Promoted Self‐Optimization and Self‐Healing of NiFe/NiMo in Alkaline Water Electrolysis

plays dual roles in the bifunctional catalysis: i) During HER, it dynamically improves the catalytic activity of NiFe-LDH by adsorbing on the surface of NiFe-LDH; ii) In OER, it can inhibit the leaching of Fe on the electrode surface or promote the re-adsorption of Fe on the electrode surface, thus contributing to the recovery of activity.
