Abstract The detection of trace impurity gases in fluorinated gas (F‐gas) that are widely used the industry offers a significant avenue for equipment status monitoring and mitigating unnecessary emissions. However, formidable electron affinity (EA) adsorption propensity F‐gas molecules render identification impurities within high‐concentration atmosphere exceptionally challenging. Herein, filtration‐sensing strategy is proposed to realize highly sensitive selective Room Temperature (RT) sensing environment. Through innovative construction bilayer structure, comprising Co 3 (HITP) 2 as overlayer SnO nanofibers (NFs) layer, remarkably under intense interference conditions achieved. efficacy further corroborated through incorporation Pd‐SnO MoS ‐SnO sensors, concurrently facilitating targeted quantitative complex mixture underlying mechanism predominantly attributed interatomic interactions modulation diffusion by microporous structures. This work provides pioneering insights into while presenting potentially viable solution operational maintenance F‐gas‐based industrial (F‐equipment) applications.
