Abstract
Surface-selenized RuO<sub>2</sub>/C (RuO<sub>2</sub>-Se<sub>0.18</sub>/C) exhibits a high NH<sub>3</sub>yield rate (12.97 μg h<sup>−1</sup>cm<sup>−2</sup>) at low overpotential. The superior NRR performance is attributed to the effects (on N<sub>2</sub>adsorption, surface hydrogenation, N<sub>2</sub>activation and NH<sub>3</sub>desorption) of surface selenization.
