摘要

Monodispersed amphiphilic zeolite/mesosilica composite material TS-1@KCC-1 (TK), which could stabilize Pickering emulsions for the benzene/H₂O₂ system, has been synthesized, and its physicochemical properties have been investigated in detail. The amphiphilic TK catalyst displayed a higher catalytic activity under Pickering interfacial catalysis (PIC) than under phase-boundary catalysis (PBC) and conventional reaction conditions in the hydroxylation of benzene by hydrogen peroxide without cosolvent and under static conditions. Under optimized conditions, a TS-1@KCC-1 catalyst grafted with octyl chains (2.42 wt %) could afford an interfacial activity of 1.1 mol (Ti-mol)^-1. Moreover, PIC reaction conditions exhibited an excellent thermal stability and good reusability.
