In this study, 2D vanadium carbide was synthesized and used as an efficient electrocatalyst for electrocatalytic N-2 reduction reaction. The catalyst showed high NH3 yield rate and Faradaic efficiency, with theoretical calculations demonstrating low reaction barrier.
Two-dimensional (2D) materials are used in energy storage and conversion due to their unique electronic structure and large specific area. In this work, 2D vanadium carbide (V2CTx MXene) is fabricated and studied as an efficient and earth-abundant electrocatalyst for electrocatalytic N-2 reduction reaction (NRR). When tested in 0.1 M Na2SO4, such electrocatalyst achieves a large NH3 yield rate of 12.6 mu g h(-1) mg(cat.)(-1) and a Faradaic efficiency of 4% at -0.7 V vs. reversible hydrogen electrode. Theoretical calculations show a low reaction barrier of 0.88 eV in the distal route for this catalyst. Graphic
