Abstract

Abstract : A novel core/shell hierarchical TS-1 zeolite has been prepared through one-pot desilication–recrystallization with the assistance of alkali and Gemini-type surfactant. Possessing multiple mesoporosities, the resultant material is highly active to alkene epoxidation. Abstract : A hierarchical titanosilicate, with epitaxially grown MFI nanosheets on microsized TS-1 crystals, has been prepared through a desilication–recrystallization method using a diammonium surfactant as the secondary structure-directing agent (SDA). This core/shell material features multiple mesoporosities, significantly improved epoxidation activity as well as easy separation in synthesis and catalytic reactions.
