A synthetic method was developed to modulate the coordination environment and regulate support architecture, thus incorporating oxygen atoms into the first shell of Co single-atom catalysts (SACs). The high activity and ¹O₂ selectivity of Co−N₃O₁ correlated with an enhanced adsorption energy of peroxymonosulfate (PMS) and reduced activation barriers. As a result, the catalysts were attached to a membrane to deliver a catalytic filter with 97.5 % ciprofloxacin rejection over 10 hours.

钴单原子锚定在氧掺杂管状碳氮化物上用于高效过氧单硫酸盐活化：同时配位结构和形态调制

开发了一种合成方法来调节配位环境和调节载体结构，从而将氧原子结合到 Co 单原子催化剂 (SAC) 的第一层中。Co-N ₃ O ₁的高活性和¹ O ₂选择性与增强的过氧单硫酸盐 (PMS) 吸附能和降低的活化势垒相关。结果，催化剂附着在膜上，以在 10 小时内提供具有 97.5% 环丙沙星截留率的催化过滤器。
