Oxygen-vacancy-containing Nb2O5 nanorods with modified semiconductor character for boosting selective nitrate-to-ammonia electroreduction

Electrocatalytic NO3− reduction to ammonia (ENRA) is a sustainable approach that allows the direct synthesis of ammonia at room temperature, while solving the problem of nitrate polluted effluents. Herein, we demonstrate that the oxygen vacancies (OVs) in Nb2O5 (Nb2O5−x) nanorods exhibit significant...
