Metal–organic frameworks (MOFs) are a class of porous organic-inorganic solids extensively explored for numerous applications owing to their catalytic activity and high surface area. In this work MOF thin films deposited in a one-step, molecular layer deposition (MLD), an all-gas-phase process, on glass wool fibers are characterized by X-ray diffraction, Fourier transform infrared spectroscopy, scanning electron microscopy, and their capabilities towards toxic industrial chemical (TIC) capture and chemical warfare agents (CWA) degradation are investigated. It is shown that despite low volume of the active material used, MOFs thin films are capable of removal of harmful gaseous chemicals from air stream and CWA from neutral aqueous environment. The results confirm that the MLD-deposited MOF thin films, amorphous and crystalline, are suitable materials for use in air filtration, decontamination, and physical protection against CWA and TIC.

利用分子层沉积制备的锆 MOF 功能化纤维基材用于有毒气体捕获和化学战剂降解

金属有机框架（MOF）是一类多孔有机-无机固体，由于其催化活性和高表面积而被广泛探索用于众多应用。在这项工作中，通过 X 射线衍射、傅里叶变换红外光谱、扫描电子显微镜和研究了它们捕获有毒工业化学品 (TIC) 和化学战剂 (CWA) 降解的能力。结果表明，尽管使用的活性材料体积较小，MOF 薄膜仍能够去除气流中的有害气态化学物质和中性水环境中的 CWA。结果证实，MLD 沉积的 MOF 薄膜（无定形和结晶）是用于空气过滤、净化和 CWA 和 TIC 物理防护的合适材料。
