摘要

In this work, DDR zeolites were synthesized by sonochemical method without the application of any heat energy at room temperature. The synthesized zeolites were characterized by X-ray diffraction (XRD), infrared (IR) spectral analysis, and field-emission scanning electron microscopy (FESEM). XRD and IR results showed that phase pure DDR zeolite was started to form at room temperature after 24 h of aging and completed the formation after 5 d of aging. The Brunauer-Emmett-Teller (BET) surface area of the powder was found to be 202 m~2/g. The FESEM micrograph and elemental analysis showed that desired atomic ratio of the DDR zeolite was obtained after 5 days of synthesis.
