Electrochemical reduction of aqueous nitrogen (N₂) at an overpotential of 0.14 V with relatively high faradaic efficiency (FE) of 0.72% is achieved on (110)-oriented Mo nanofilm. A rate of NH₃ formation as high as 3.09 × 10⁻¹¹ mol s⁻¹ cm⁻² can be obtained under an applied potential of −0.49 V (vs. reversible hydrogen electrode, RHE). This is a record-high activity, higher than that reported in previous experimental results under comparable reaction conditions.

在（110）取向的Mo纳米膜上以低超电势电化学还原含水氮（N ₂）

在（110）取向的Mo纳米膜上实现了以0.14 V的超电势以0.72％的相对较高的法拉第效率（FE）电化学还原水氮（N ₂）。在-0.49 V的施加电势下（相对于可逆氢电极，RHE），可以获得高达3.09×10 ^-11 mol s ^-1 cm ^-2的NH ₃形成速率。这是创纪录的高活性，高于在可比的反应条件下以前的实验结果所报道的活性。
