C s ‐Corrected STEM Imaging of both Pure and Silver‐Supported Metal‐Organic Framework MIL‐100(Fe)

Abstract Metal‐organic frameworks (MOFs) are a family of porous solids combining organic and inorganic moieties with tunable porosity. Their structural parameters have converted MOFs into suitable compounds for gas storage or drug delivery. However, despite the excellent crystallinity they tend to e...

Summary:Abstract Metal‐organic frameworks (MOFs) are a family of porous solids combining organic and inorganic moieties with tunable porosity. Their structural parameters have converted MOFs into suitable compounds for gas storage or drug delivery. However, despite the excellent crystallinity they tend to exhibit their analysis through transmission electron microscopy is extraordinarily complicated owing to the high instability under the electron beam irradiation. In here, high‐resolution C s ‐corrected STEM imaging was used for the observation of the building units of MIL‐100(Fe), and special attention was paid to the electron beam current. In addition, MIL‐100(Fe) was reacted with AgNO 3 through a solid‐state reaction technique, which resulted into the formation of metal nanoparticles on the surface. The incorporation of Ag into the porous network has been also investigated.
