In this thesis, B-type sandwich polyoxometalate of [(PW9O34)2Fe4(H2O)2]6- was immobilized into porous composite cavities of Cr-MIL-101 by simple anion exchange[1, 2]. The formation of P2W18Fe4@MIL-101 nanocomposite was confirmed by FT-IR, TGA, BET, SEM, EDX, ICP, BET and powdery XRD methods. The catalytic activity of nanocomposites was investigated in oxidation of sulfides to sulfons with H2O2 at room temperature [3]. The effect of temperature on stability and catalytic activity of the P2W18Y3@MIL-101 was investigated. The effects of different dosages of catalyst, type of solvent, reaction time, amount of oxidant in this catalytic system were investigated. The new P2W18Fe4@MIL-101 nanocomposite exhibited well recyclability and reusability in at least five consecutive reaction cycles without significant loss of activity or selectivity.
