What is UiO-66 MOF?

UiO-66 is an archetypal metal–organic framework (MOF) with a very high surface area as well as high thermal stability. It is found that the stability can be attributed to the metal oxide node being cuboctahedral allowing for 12 extension points for 1,4-benzenedicarboxylic acid (BDC) coordination.

How do you make a UiO-66?

Synthesis of UiO-66 is using solvotermal methods in the oven at 140°C with a variation of heating time at 6, 12, 24, 36, 48, 72, and 144 hours to give a solution with two layers of white solid on the bottom and the clear solution at the top.

What is mil in MOFs?

MIL-53 (MIL ⇒ Matériaux de l′Institut Lavoisier) belongs to the class of metal-organic framework (MOF) materials. The first synthesis and the name was established by the group of Gérard Férey in 2002. effect’ and describes the ability of the MIL-53 framework to respond to external stimuli.

What is material Institute Lavoisier?

Consequently, it is imperative to develop stable and high-performance light-responsive catalysts. MIL (Materials Institute Lavoisier) materials are porous metal carboxylate salts composed of different trivalent metal cations and carboxylic acid ligands with huge pore and permanent porosity [23], [24].

What are MOFs made from?

Metal-organic frameworks (MOFs) are organic-inorganic hybrid crystalline porous materials that consist of a regular array of positively charged metal ions surrounded by organic ‘linker’ molecules. The metal ions form nodes that bind the arms of the linkers together to form a repeating, cage-like structure.

Are MOFs soluble?

Present invention discloses biocompatible metal-organic frameworks (MOFs) of formula I that combine a metal and a derivative of an amino acid. Particularly, the invention discloses MOFs of a metal and a derivative of an amino acid which are water soluble.

What is mil in MOF?

MIL-53 (MIL ⇒ Matériaux de l′Institut Lavoisier) belongs to the class of metal-organic framework (MOF) materials. The first synthesis and the name was established by the group of Gérard Férey in 2002.

What is mil in chemistry?

a unit of measure that equals one-thousandth of an inch. [ SEMATECH]

What is the adsorption capacity of UiO-66?

The maximum adsorption capacities of pristine UiO-66 for anionic methyl red (MR) (384 mg/g) and methyl orange (MO) (454 mg/g) dyes were slightly higher than those of the cationic malachite green (MG) (133 mg/g) and methylene blue (MB) (370 mg/g) dyes, particularly at lower pH values.

Is UiO-66 a good anionic dye?

UiO-66 showed excellent structural stability against water, chloroform and dimethylformamide. Pristine UiO-66 and its solvent aged samples showed good selectivity for anionic dyes against cationic dyes. UiO-66 exhibited the highest adsorption selectivity for anionic dyes after aging in water for 12 months.

What happens to UiO-66 in water and chloroform?

The UiO-66 crystalline structure remained unchanged in water and chloroform, while XRD patterns of UiO-66 aged in DMF showed only a minor change, which might be due to the partially exterior framework collapse.

What is the peak intensity of uio-66-nh2?

The XRD pattern of UiO-66-NH 2, synthesized in different reaction times (figure 1 (b)), contained characteristic peaks of UiO-66 at 2 θ = 7.34°, 8.48° [ 14 – 17] with different intensity dependences on the reaction times. The variation of peak intensity has extreme character.
