Zeolite L with a Si/Al moles ratio of 1.9 was synthesized from initial concentrated gel in the absence of organic templates. The crystallization behavior and the crystal microstructure during crystallization were analyzed by X-ray diffraction, scanning electron microscopy, transmission electron microscopy, nitrogen adsorption-desorption and energy dispersive X-ray spectroscopy. The effects of synthesis parameters such as synthesis time, aging time and molar compositions on the crystal growth were investigated. The results show that as-synthesized zeolite nanocrystals possess hierarchical structure. Pure zeolite L with a high crystallinity was obtained within a wide ratio range of gel SiO2/Al2O3 of 20-100. Moreover, the adsorption performance of the samples under the optimized synthesis conditions were evaluated via the equilibrium adsorption of pure gases CO2, CH4 and N2 at 25 ℃. Zeolite nanocrystals exhibit a high CO2 adsorption capacity.
