In this issue of Chem Catalysis, Wang et al. have synthesized a single-atom Au₃Fe₁/Mo alloy featuring medium-spin Fe(III) through an alloying strategy to enhance plasmonic nitrogen fixation. The enhancement mechanism has been found to originate from the medium-spin Fe centers acting as active sites that facilitate the adsorption and activation of nitrogen molecules.

控制电子自旋状态以增强等离子体固氮

在本期《化学催化》中，王等人。通过增强等离子体固氮的合金化策略，合成了具有中等自旋 Fe(III) 的单原子 Au ₃ Fe ₁ /Mo 合金。研究发现，这种增强机制源于中自旋铁中心作为活性位点，促进氮分子的吸附和活化。
