Encapsulated phosphomolybdic acid in TMU-16 metal organic framework: Study the catalytic activity and structural stability dependent on synthetic solvent
Encapsulated phosphomolybdic acid in the TMU-16, HPMA@TMU-16, at three different solvents was synthesized and characterized. For characterization studies XRD, ICP, TGA, CHNS, BET, SEM-EDS and TEM methods were used. Evidences such as loss of specific surface area, EDS elemental mapping and similar XRD patterns confirmed that HPMA to be import in the TMU-16 pores. A catalytic activity of samples was performed in the oxidation of sulfides and optimum conditions were studied in the dibenzyle sulfide oxidation reactions. Obtained results including short reaction times, selectivity to sulfoxide and reusability exhibited high performance of HPMA@TMU-16 as heterogeneous catalyst. Increasing number of recovered cycles with shorter reaction times revealed effect of polarity of synthetic solvent on the catalytic activity and structural stability.
