Through the catalysis system design of Ru SACs (single atoms) anchored on a rGO/NC two-dimensional interface, we successfully realized the SA-Ru@rGO/NC electrocatalyst with high metal loading density at a relatively low temperature. The largest NH yield of 110.1 μg h mg and FE of 17.9% were achieved at -0.3 V under ambient conditions. The electronic environment of the catalyst was regulated by the electronic metal-support interaction, and the use of SACs had the advantages of inhibiting the hydrogen evolution reaction (HER) and enhancing N adsorption, which effectively improved the performance of electrocatalytic nitrogen fixation.
通过 Ru SACs（单原子）锚定在 rGO/NC 二维界面的催化体系设计，我们成功地在相对较低的温度下实现了具有高金属负载密度的 SA-Ru@rGO/NC 电催化剂。在环境条件下，-0.3 V 时最大 NH 产量为 110.1 μg h mg，FE 为 17.9%。催化剂的电子环境通过电子金属-载体相互作用进行调节，使用 SACs 具有抑制析氢反应（HER）和增强 N 吸附的优点，这有效地提高了电催化固氮的性能。
