The electrochemical nitrogen reduction reaction (NRR) is a promising approach to convert N into high value-added NH. However, it is still a challenge to achieve an efficient electrocatalyst for the NRR. Herein, it is demonstrated that the FeO nanoparticles (NPs) generated from a glycerine-based synthesis can be applied as highly efficient catalysts for the NRR. The FeO NPs show good performance with a high NH yield (22 μg mg h) and a favorable Faradaic efficiency (FE) (3.5%) at -0.5 V reversible hydrogen electrode (RHE). The facile synthesis strategy and satisfactory electrochemical properties demonstrate the potential application of the as-synthesized FeO NPs for NRR.
电化学氮还原反应（NRR）是一种将氮转化为高附加值氨的有前景的方法。然而，实现用于NRR的高效电催化剂仍然是一项挑战。在此，证明了通过基于甘油的合成方法生成的FeO纳米颗粒（NPs）可作为用于NRR的高效催化剂。FeO NPs在-0.5 V可逆氢电极（RHE）下表现出良好的性能，具有高氨产率（22 μg mg⁻¹ h⁻¹）和良好的法拉第效率（FE）（3.5%）。这种简便的合成策略和令人满意的电化学性能证明了所合成的FeO NPs在NRR中的潜在应用。
