To develop highly efficient electrochemical catalysts for N₂ fixation is important to sustainable ambient NH₃ production through the N₂ reduction reaction (NRR). Herein, we demonstrate the development of vanadium phosphide nanoparticle on V foil as a high-efficiency and stable catalyst for ambient NH₃ production with excellent selectivity. The high Faradaic efficiency of 22% with a large NH₃ yield of 8.35 × 10⁻¹¹ mol·s⁻¹·cm⁻² was obtained at 0 V vs. the reversible hydrogen electrode in acid solution, superior to all previously studied V-based NRR catalysts. Density functional theory calculations are also utilized to have an insight into the catalytic mechanism.

开发用于N ₂固定的高效电化学催化剂对于通过N ₂还原反应（NRR）可持续生产周围NH ₃至关重要。在本文中，我们证明了V箔上磷化钒纳米粒子的发展，它是一种高效，稳定的催化剂，用于环境NH _3的生产，具有出色的选择性。高达22％的法拉第效率，NH ₃收率高达8.35×10 ^-11 mol·s ^-1 ·cm ^-2与酸性溶液中的可逆氢电极相比，在0 V时可获得的碳原子数要优于以前研究的所有基于V的NRR催化剂。密度泛函理论计算也可用于深入了解催化机理。
