Abstract
P doping greatly improves electrochemical N<sub>2</sub> reduction over graphene. In 0.5 M LiClO<sub>4</sub>, P-doped graphene attains a high Faradic efficiency of 20.82% and a large NH<sub>3</sub> yield of 32.33 μg h<sup>−1</sup> mg<sub>cat.</sub><sup>−1</sup> at −0.65 V <italic>vs.</italic> RHE.
