A simple amphiphilic surfactant containing a mono-quaternary ammonium head group (N-methylpiperidine) is effective in imparting substantial mesoporosity during synthesis of SSZ-13 and ZSM-5 zeolites. Highly mesoporous SSZ-13 prepared in this manner shows greatly improved catalytic performance in the methanol-to-olefins reaction compared to bulk SSZ-13.
一种含有单季铵头基（N-甲基哌啶）的简单两亲性表面活性剂在合成SSZ-13和ZSM-5沸石的过程中能有效地赋予大量介孔。与块状SSZ-13相比，以这种方式制备的高度介孔SSZ-13在甲醇制烯烃反应中表现出大大提高的催化性能。
