Abstract
Fe-doping induced synergetic effects, including the morphological change of crystalline CeO<sub>2</sub> to partial-amorphous nanosheets, enriched O-vacancies and active Ce<sup>3+</sup>–Ce<sup>3+</sup> pairs, were all responsible for the significantly enhanced NRR activity of Fe-CeO<sub>2</sub>.
