- Abstract
- The direct encapsulation of tungstophosphoric acid (PW12) into MIL-101 was done (PW12@MIL(101)en). The addition of PW12 to the synthesis mixture of MIL-101 yielded the direct encapsulation of chromium-containing polyoxometalates (POMs) inside the metal organic framework (MOF) structure, with a good distribution over the MIL-101 crystals. Another PW12 composite (PW12@MIL(101)im) was prepared via the impregnation of the polyoxometalate in MIL-101. The structural and textural characterizations of PW12@MIL(101) were done using FTIR, X-ray diffraction, N2 adsorption-desorption, and TEM. XRD and adsorption–desorption analysis showed that the mesostructure of MIL-101 remains intact after vanadium oxide modifications, while spectral technique showed the successful immobilizing of the neat vanadium oxide inside the MIL-101 cavities. PW12@MIL(101) has emerged as highly efficient and heterogeneous catalyst for selective oxidation of sulfides to sulfoxides and sulfones because of its high specific surface area, tuneable pore size, and unique structure.
