Abstract

Abstract: 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. Abstract : Glass fibers coated with amorphous and crystalline amino‐functionalized Zr‐metal‐organic‐frameworks (Zr‐MOF) films show activity towards capturing NH3 and enabling the catalytic degradation of nerve agents. A novel, one‐step molecular layer deposition method is used for direct fiber coating. This indicates the potential of Zr‐MOF functionalized fibrous materials for improved decontamination methods and protective equipment against various toxic chemicals.
