Abstract

Using tetrahexahedral gold nanorods as a heterogeneous electrocatalyst, an electrocatalytic N<sub>2</sub> reduction reaction is shown to be possible at room temperature and atmospheric pressure, with a high Faradic efficiency up to 4.02% at -0.2 V vs reversible hydrogen electrode (1.648 µg h<sup>-1</sup> cm<sup>-2</sup> and 0.102 µg h<sup>-1</sup> cm<sup>-2</sup> for NH<sub>3</sub> and N<sub>2</sub> H<sub>4</sub> ·H<sub>2</sub> O, respectively).
