英文摘要A series of emulsion catalysts were successfully synthesized with quarternary ammonium cations and heteropolyanions, and they were characterized by TG/DTA, FTIR, (31)P MAS NMR and EPR. The emulsion catalyst with intact Keggin-structure, [C(18)H(37)N(CH(3))(3)]H(2)[PW(12)O(40)] (PW(12)), is inactive for benzothiophene (BT) oxidation with H(2)O(2) as oxidant under atmospheric pressure at 30 C. Moreover, the metal-substituted catalysts PW(11)M (M =Ti, Mn, Fe, Co, Ni and Cu) show rather low activity with the conversion less than 15% for BT oxidation. Whereas, the catalyst with mono-lacunary Keggin-structures, [C(18)H(37)N(CH(3))(3)](5)Na(2)[PW(11)O(39)] (PW(11)), could completely catalytic oxidize BT into the corresponding sulfone under the same conditions. After careful characterizations of the catalysts, it is found that only PW(11) catalyst could effectively transform into the active polyperoxometalates species in the presence of hydrogen peroxide in non-polar solvent.
