Facile Synthesis and Direct Activation of Zirconium Based Metal–Organic Frameworks from Acetone
In recent years much emphasis has
been placed on the synthesis
of highly novel metal–organic frameworks (MOFs) with general
disregard to development of sustainable synthesis techniques. A novel
synthesis of UiO-66 and UiO-66-NH<sub>2</sub>, two highly stable MOFs
that have shown much promise in the area of catalysis and reactive
removal of small molecules, from acetone is demonstrated here. Using
this method, the MOFs can be activated by simple heating under vacuum
without the need for solvent exchange, which can be a timely processing
step that requires the use of large amounts of solvent. The activity
of the series of MOFs synthesized at various temperatures was determined
by the rate of hydrolysis of methyl paraoxon and the reactive capacity
of UiO-66-NH<sub>2</sub> with chlorine gas. Direct correlations were
observed between synthesis temperature, crystallinity, BET surface
area, and activity of the MOFs
