Abstract: Single crystal zeolite L rods with high aspect ratio have been prepared using rice husk ash as silica source in the presence of other aqueous-based precursors via a single-step hydrothermal process at 170 oC for 72 h. Crystallization behavior of the particles is studied by X-ray diffraction, and the characteristic vibration bands of zeolite L are confirmed by FTIR spectroscopy. BET surface area and total pore volume of the particles are found to be 142 m2 g-1 and 0.19 cm3 g-1, respectively. Rod-shaped morphology of zeolite L with an aspect ratio of 10-50 is observed by FESEM and TEM. Selected area electron diffraction pattern of TEM confirms the single crystal nature of the particles.
