Abstract
Metal-organic-frameworks (MOFs) with large specific surface area, tunable pore size,
versatile structures, functionality, and relative thermal and chemical stability, have applications
in a wide range of topics from adsorption, catalysis, environment and medicine, and electronic
devices.
The metal gel to MOFs conversion strategy, initially developed from ZIF-8 and MOF-5
aerogels synthesis in this study, has been extended to other tens of MOF aerogels synthesis
with discussion of correlation between detailed conversion parameters and resulted properties.
The as-prepared MOF aerogels possess high specific surface area, crosslinking networks, and
mesoporous channel allowing improved mass diffusion and transportation. A mechanism for
this methodology has been revealed based on a se...[

with discussion of correlation between detailed conversion parameters and resulted properties.
The as-prepared MOF aerogels possess high specific surface area, crosslinking networks, and
mesoporous channel allowing improved mass diffusion and transportation. A mechanism for
this methodology has been revealed based on a series of MOF aerogel exploration, and also
found to be facile for fabricating magnetic Fe
3O
4-ZIF-8 recyclable mesoporous adsorbents for
efficient removal of methylene blue and diclofenac from aqueous media, and it was two times
higher than that of activated carbon in terms of adsorption capacity. The small sized magnetic
colloids has also been successfully incorporated into ZIF-8 crystals, which allowed high
loading of ferulic acid (556 mg/g) and slow release rate (62% in 4 days) at blood circulation
pH and fast release at acidic conditions, exhibiting the great potential as a targeted drug carrier.
Additionally, the solutions for utilizing MOFs in presence of moisture and more server
mechanical circumstance have been built, two individual routes for preparing highly
compressible and hydrophobic porous aerogel-like MOF monoliths were well investigated
firstly to the best of our knowledge and showed the satisfactory results upon utilization in
gaseous and liquid components removal. The work may open scientific and industrial prospects
for MOFs in practical applications.
