| Abstract: | Microporous AlPO₄-zeolites have been synthesized in the presence of glycine and alanine under mild hydrothermal conditions, maintaining temperature at 150ºC under autogeneous pressure. Reaction mechanism has been proposed for the crystallization process. The use of amino acids results in tremendous effects on the pore size of AlPO₄-zeolites. The cell volume and surface area are increased while the void fraction is decreased. The products have been characterized using XRD, FTIR, Positron annihilation life time techniques and BET surface area analysis. Scanning electron micrographs show the morphological and structural changes when alanine and gylcine are used as structure directing agents or templates. |
