Immobilization of polyoxometalates in the Zr-based metal organic framework UiO-67

The encapsulation of polyoxometalates within the large pores of the Zr( iv ) biphenyldicarboxylate UiO-67 metal-organic framework has been achieved, for the first time, by direct solvothermal synthesis. The resulting POM@UiO-67 composite materials were fully characterized by XRPD, IR, MAS NMR, N 2 porosimetry measurements and cyclic voltammetry. We report the successful synthesis of several POM@UiO-67 composites and their characterization by a panel of complementary techniques.
