Confined-based catalyst investigation through the comparative functionalization and defunctionalization of Zr-MOF

Abstract

In metal–organic frameworks, confined space as a chemical nanoreactor is as important as organocatalysis or coordinatively unsaturated metal site catalysis.

A comprehensive study about functionalization and de-functionalization of MOF-808 as a defect-engineered Zr-MOFs for selective catalytic oxidation

“…Regarding samples obtained from the exchanged-ligand method, the surface charge is more negative than the mixing-ligand method. This analysis shows that in the exchange method, the highest exchange rate is done at the surface of the nanoparticles, and as a result, the amount of defect and functional groups is higher at the surface, which also affects the catalytic activity [ 40 , 41 ].…”

Sensitive determination of 4,6-dinitro-o-cresol based on a glassy carbon electrode modified with Zr-UiO-66 metal–organic framework entrapped FMWCNTs

“…Other absorption bands obtained are assigned to C]O stretching (1600 cm −1 ), N-H bending (1400 cm −1 ), aromatic C-N stretching (1300 cm −1 ), and Zr-O vibrational bands (600 cm −1 ). 42,43 Spectra of MWCNTs (Fig. 1B-c) show intense peaks at 3430 cm −1 (attributed to OH stretching of COOH originating from reactions of MWCNTs with the atmosphere), 2915 cm −1 (C-H stretching of alkyl and aromatic compounds), 2840 cm −1 (deformation of aromatic compounds), and 1660-479 cm −1 (C]O and C]C stretching and their deformations).…”

Photocatalytic aerobic oxidative functionalization (PAOF) reaction of benzyl alcohols by GO-MIL-100(Fe) composite in glycerol/K2CO3 deep eutectic solvent

“…As the most attractive porous materials, metal–organic frameworks (MOFs) have captured incredible attention in the last decade. Unique features such as purposeful and programmable architecture, structural diversity, large surface area, applicability in chemical sensing, separation, gas absorption and storage, and, most importantly, catalysis have multiplied the importance of these frameworks 24 – 27 . However, the bearing fruit use of MOF-based optical elements and devices has been (hampered) limited by disadvantages such as low light absorption and high charge-transfer resistance.…”
