英文摘要catalysts assembled in emulsions are found to be potentially recoverable and efficient for a number of catalytic reactions. the catalysts composed of polyoxometalate anions and quaternary ammonium cations have been designed and synthesized according to the catalytic reactions and by optimizing the structures of cations and anions. the catalysts act essentially as surfactants, which are uniformly distributed in the interface of the emulsion droplets, and accordingly behave like homogeneous catalysts. the catalysts show remarkable selectivity and activity in the oxidation of sulfur-containing molecules to sulfones in diesel and the selective oxidation of alcohols to ketones, using h2o2 as oxidant. for an example, the catalyst demonstrated over 96% efficiency of h2o2 and similar to 100% selectivity to sulfones for the selective oxidation of sulfur-containing molecules in real diesel. moreover, the catalysts can be separated and recycled by a simple demulsification and re-emulsification.
