Fe-doping induced morphological changes, oxygen vacancies and Ce3+–Ce3+ pairs in CeO2 for promoting electrocatalytic nitrogen fixation

Developing active and robust catalysts for the electrocatalytic N2 reduction reaction (NRR) represents a promising strategy for ambient NH3 production but remains challenging. Herein, CeO2 was modulated by Fe-doping for the NRR in neutral media. Fe-doping was found to induce the morphological change...
