Abstract
Abstract The aqueous electrocatalytic reduction of NO 3 − into NH 3 (NitrRR) presents a sustainable route applicable to NH 3 production and potentially energy storage. However, the NitrRR involves a directly eight‐electron transfer process generally required a large overpotential (<−0.2 V versus reversible hydrogen electrode ( vs . RHE)) to reach optimal efficiency. Here, inspired by biological nitrate respiration, the NitrRR was separated into two stages along a [2+6]‐electron pathway to alleviate the kinetic barrier. The system employed a Cu nanowire catalyst produces NO 2 − and NH 3 with current efficiencies of 91.5 % and 100 %, respectively at lower overpotentials (>+0.1 vs . RHE). The high…
