With the development of ultralow-dose (scanning) transmission electron microscopy ((S)TEM) techniques, atomic-resolution imaging of highly sensitive nanomaterials has recently become possible. However, applying these techniques to the study of sensitive bulk materials remains challenging due to the lack of suitable specimen preparation methods. We report that …

When used to degrade 20 mg L-1 hexavalent chromium in aqueous solution, the Fe-MOFs were found to completely reduce a 100 mL solution within 120 min under natural light and a 400mL solution within 90 min under Xe lamp irradiation. Fe-Based metal-organic frameworks (Fe-MOFs) were prepared with trimesic acid and FeSO4·7H2O via a microwave-assisted ball milling …

Fe-Based metal-organic frameworks (Fe-MOFs) were prepared with trimesic acid and FeSO·7HO via a microwave-assisted ball milling approach. The structure and thermal stability of the as-prepared Fe-MOFs were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), Fourier transform infrared spectrometry (FTIR), X-ray photoelectron spectroscopy …

The in-situ monitoring of MOFs by ball milling is an indispensable requirement for the in-depth study of the ball milling reaction [35,51,53,60,71,106]. Although many kinds of MOFs have been successfully synthesized by ball milling, the understanding of the reaction mechanism of these MOFs is still insufficient.

Zn-based triazole-rich energetic MOFs encapsulated with Co and Fe species were used as precursors. After high-temperature pyrolysis, zinc nodes were reduced and volatilized, while MOFs formed a hierarchical porous carbon network. Meanwhile, evenly dispersed Fe and Co target metal ions were uniformly dispersed into the carbon grid.

Abstract In this study, we prepared Zn-MOFs as an ordinary, low-cost, and efficiency method taking advantage of zinc(ii) acetate monohydrate and 1,3,5-benzenetricarboxylic acid in microwave-assisted ball milling. The Zn-MOFs were measured via scanning electron microscopy, infrared spectrometry, X-ray diffraction, and thermogravimetry. We explored its use as a …
