An amphiphilic composite material of titanosilicate@mesosilica/carbon as a Pickering catalyst†
Abstract
A hierarchically core/shell-structured TS-1@silica/carbon composite material, synthesized from titanosilicate crystals and surfactant-mediated mesosilica/resol precursors via a self-assembly and nanocasting route, was fabricated to produce stable oil–water–solid Pickering emulsions in alkene/H2O2 media, exhibiting attractive interfacial activity and stability for selective epoxidation of alkenes.
