Abstract: Clear solution was prepared by hydrolyzing tetraethylorthosilicate (TEOS) in tetrapropylammonium (TPA) hydroxide and heated at 120 ° C for various times in order to generate half-nanoslabs, nanoslabs, tablets, intermediates and colloidal Silicalite-1 crystals. These building units were precipitated by addition of cetyl trimethyl ammonium (CTMA) bromide. After evacuation of TPA and CTMA from the precipitates through calcination, microporous materials having substantial micropore volumes of 0.5-0.7 ml/g designated as Zeogrids were obtained. The micropores comprise ultra-micropores inside the zeolitic building units, and super-micropores between these building units. The ultra-micropores of Zeogrids render molecular sieving properties to these materials, which can be fine-tuned by adapting the size of the zeolitic building units. © 2005 Academie des sciences.
