Abstract

IBN-9 is the first tricontinuous mesoporous material, consisting of three identical interpenetrating channels that are separated by a single continuous silica wall. It was originally synthesized using a specially designed surfactant as template. The need of special surfactant in the synthesis inhibits extensive investigation of this novel structure and its applications. We demonstrate in this study that such a complicated tricontinuous mesostructure can also be fabricated from the most common and commercially available surfactant cetyltrimethylammonium bromide (CTAB) with the help of polar organic additives, e.g., n-butanol. The role of n-butanol is to finely tune the surface curvature of the organic/inorganic interface during the cooperative self-assembly process. Electron microscopic techniques are employed to identify different mesostructures from the mixture. This study reveals the possibility of discovering unprecedented mesostructures from conventional surfactant-water- silicates systems. © 2011 American Chemical Society.
