An atomic layer deposition approach precisely tunes the nuclearity of Fe sub-nanocatalysts anchored on N,O-doped carbon nanorods. The electronic properties and spin configuration of the sub-nanocatalysts are nuclearity dependent and dominate H₂O₂ activation modes and the adsorption strength of active O species on Fe sites during C−H oxidation. The single-atom catalyst, Fe₁-NOC, achieves state-of-the-art activity for benzene oxidation.

利用自旋态控制的核效应对铁亚纳米催化剂促进苯氧化

原子层沉积方法可精确调节固定在 N、O 掺杂碳纳米棒上的 Fe 亚纳米催化剂的核度。亚纳米催化剂的电子特性和自旋构型依赖于核度，并在 C-H 氧化过程中主导 H ₂ O ₂活化模式和活性 O 物种在 Fe 位点上的吸附强度。单原子催化剂 Fe ₁ -NOC 实现了最先进的苯氧化活性。
