| 英文摘要 | efficient and stable solid acids have been successfully synthesized by sulfonation of polystyrene (ps) in the hollow interiors of silica-based hollow nanostructures. it was found that larger and smaller inner void spaces result in the formation of ps-so3h@phenylenesilica respectively with double-shell (dsns) and yolk-double-shell nanostructure (ydsns). ps-so3h@phenylenesilica with dsns and ydsns nanostructure shows comparable activity and is more active than amberlyst-15 in the esterification reaction. ps-so3h@phenylenesilica with ydsns nanostructure affords higher activity than that with dsns nanostructure in the friedel-crafts alkylation of toluene with 1-hexene, which is mainly attributed to the fact that the unique ydsns nanostructure could slow down the swelling rate of ps-so3h during the catalytic process. more importantly, ps-so3h@phenylenesilica with ydsns nanostructure showed much higher recycle stability than amberlyst-15 in the friedel-crafts alkylation of toluene with 1-hexene, probably due to the high thermal stability of the sulfonic acid group and the unique ydsns nanostructure.
