Electrodeposition of Cu on NiCo<sub>2</sub>O<sub>4</sub> nanoarrays for efficient electrochemical nitrate reduction to ammonia
For electrochemical nitrate reduction to ammonia, non-noble metal-based catalysts with excellent performance are highly desirable. Herein, a Cu-NiCo<sub>2</sub>O<sub>4</sub> electrocatalyst was constructed by facile electrodeposition of Cu on NiCo<sub>2</sub>O<sub>4</sub>. When performed in alkaline solution, Cu-NiCo<sub>2</sub>O<sub>4</sub> achieved a high NH<sub>3</sub> yield of 3.56 mmol h<sup>-1</sup> cm<sup>-2</sup> and NH<sub>3</sub> faradaic efficiency of 95.2% at -0.2 V <i>vs.</i> RHE.
