A Co single-atom catalyst was synthesized via thermal decomposition of a zeolitic imidazolate framework (ZIF). The Co1−N4@NC catalyst generated a stable Co−F intermediate in situ through an oxidative fluorination pathway to replace the substitution fluorination of the unstable high-valent Co system. In the presence of Co−F intermediates, KF can be used to replace AgF. Co1−N4@NC exhibited ultrahigh
通过沸石咪唑酯骨架(ZIF)的热分解合成了Co单原子催化剂。Co 1 -N 4 @NC 催化剂通过氧化氟化途径原位生成稳定的 Co-F 中间体,以取代不稳定的高价 Co 体系的取代氟化。在存在 Co-F 中间体的情况下,KF 可用于替代 AgF。Co 1 -N 4 @NC 对酰氯的氟化具有超高的催化活性。
