Abstract
ZrO<sub>2</sub> nanoparticles act as an efficient electrocatalyst for ambient N<sub>2</sub>-to-NH<sub>3</sub> fixation. In 0.1 M HCl, it attains a large NH<sub>3</sub> yield rate of 24.74 μg h<sup>−1</sup> mg<sub>cat.</sub><sup>−1</sup> with a faradaic efficiency of 5.0% at −0.45 V <italic>vs.</italic> RHE.
