Gd‐Induced Oxygen Vacancy Creation Activates Lattice Oxygen Oxidation for Water Electrolysis

open access: yesAdvanced Functional Materials, EarlyView.
DFT calculations shows that Gd incorporation into Fe‐doped NiO raises the O 2p band center, lowers oxygen vacancy formation energy, and thus promotes the LOM mechanism for OER. Gd and Fe co‐doped NiO nanosheets synthesized via spray combustion exhibits a low overpotential of 227 mV and maintains stable AEMWE performance for over 120 h, demonstrating ...
