Easily recoverable micron-sized silica-walled TS-1 colloidosomes: Preparation and application as liquid-phase alkene epoxidation catalysts

Abstract Ultrafine hierarchical TS-1 zeolite ( w/o ) and ratio of TS-1 wt to oil volume (R s/o ). On the same time, X-ray diffraction patterns and UV–vis spectra disclosed that the interfacial sol-gel process had no effect on the MFI structure of hierarchical TS-1 particles. The catalytic results showed that the prepared TS-1 colloidosome was a very active and stable catalyst for liquid-phase alkene epoxidation reactions.
