Abstract
Core-shell structured ZSM-5 zeolites (CSSZs) consisting of a micro-macroporous zeolite core and a mesoporous zeolite shell were synthesized by using a bifunctional surfactant containing an alkene group in the hydrophobic tail. The alkene tail and aluminum concentration are the key factors for the formation of the mesoporous shell in CSSZs.
摘要
核壳结构 ZSM-5 沸石（CSSZs）由微-介孔沸石核和介孔沸石壳组成，通过使用疏水尾链中含有烯烃基团的双功能表面活性剂合成。烯烃尾链和铝浓度是 CSSZs 中形成介孔壳的关键因素。
