Supramolecular Microporous and Nanoporous Materials Synthesized in the Mixed Micellar Solutions

초록

Ordered mesoporous materials with excellent hydrothermal stability have been prepared by sequential synthesis of MCM-41 mesoporous frame and ZSM-5 microporous frameworks using a mixture of amphiphilic block copolymer, poly(ethylene oxide)-b-poly(propylene oxide)-b-poly( ethylene oxide) (EO20PO70EO20, numbers in subscripts denote the molar ratios of each component) and cetyltrimethylammonium bromide, C16H13(CH3)3NBr (CTAB) as a structure directing agent.
