A series of Al-Silicalite-1, Ge-Silicalite-1 and Ge,Al-Silicalite-1 samples have been synthesized in both hydroxide an fluoride media and characterized using numerous methodologies. The effect of synthesis pH, particularly in the case of hydroxide media, on the inclusion of germanium and crystal morphology will be discussed. Beyond methods including IR, 29Si NMR, 27Al NMR, XRD and nitrogen adsorption the authors will report 13C and 1H NMR of probe molecules bound to acid exchanged samples. These results, along with catalytic testing data of the catalysts will be presented. We will also present our initial attempts to locate framework germanium atoms via single crystal diffraction studies of large germanium-containing silicalite-1 crystals.
