China UIO-66 Powder Metal Organic Frameworks (MOFs) - Leading Suppliers and Factory for Advanced Applications

This crystal is a face-centered-cubic structure containing an fm-3m symmetry with a lattice parameter of 20.7 Å. It contains two separate cages, a tetrahedron cage of 7.5 Å, another an octahedron cage of 12 Å, and a pore aperture of 6 Å. The theoretical pore volume of UiO-66 is 0.77 cm3/g, and the surface area is 1160 m2/g. UiO-66 is of the fcu topology. The use of this system for MOFs includes defining the inorganic node as a secondary building unit (SBU) and classifying the zirconium oxide node in UiO-66 as cuboctaherdral, allowing up to 12 points of extension for BDC struts to coordinate.

Half of the eight oxygen atoms in the hydroxylated version of this SBU are bound to three zirconium atoms as individual atoms, and the remaining oxygen atoms are bound to three zirconium atoms in hydroxide form. UiO-66 is known for its high stability and coordination. The highly tunable nature of this exceedingly stable MOF allows strategies such as doping and postsynthetic modifications to add functionalities for their specific applications. It is anticipated that this research will continue to advance into many different fields as there have been many exciting prospects for the application of UiO-66 in areas such as catalysis, photocatalysis, adsorption separation, sensors, and even in biomedicine.
