Metal–organic framework-derived shuttle-like V2O3/C for electrocatalytic N2 reduction under ambient conditions

Author affiliations

Abstract

Electrocatalytic N2 reduction under ambient conditions is a promising alternative to the traditional Haber–Bosch process for environmentally benign and sustainable NH3 production but requires efficient electrocatalysts for the N2 reduction reaction (NRR). Here, we report that metal–organic framework-derived shuttle-like V2O3/C acts as an outstanding NRR electrocatalyst for N2-to-NH3 conversion with excellent selectivity under ambient conditions. In 0.1 M Na2SO4, such V2O3/C exhibits a remarkable NH3 yield of 12.3 μg h−1 mg−1cat. and a high faradaic efficiency of 7.28% at a potential of −0.6 V versus reversible hydrogen electrode, outperforming most of the reported aqueous-based NRR electrocatalysts. Notably, it also shows high electrochemical and structural stability.
