SYNTHESIS OF METAL ORGANIC FRAMEWORKS MATERIALS CONTAINING ZICONIUM WITH DEFECTIONS IN FRAMEWORKS

Abstract

Defected Metal organic frameworks materials containing ziconium Zr (UiO-
66, UiO-66@Ti and UiO-66-NH2) have been successfully hydrothermal
synthesized by using benzoic acid as modulators also by incoporated Titanium
ions in to frame- works at atmospheric pressure. The products were
characterized by modern analysis techniques such as: BET, IR, EDX,TGA and XRD.
Obtained results showed out defections were created in materials frameworks
which would play an important role for enhance absorption capacity and
catalytic activeties of these modified materials. From N2 adsorption (BET) shows
that Zr-UiO-66, Zr-UiO-66 defect, Zr-UiO-66@Ti and UiO-66-NH2 with high
surface area 597.38m2/g, 781.17m2/g, 766.98m2/g và 606.25m2/g.
