Abstract: | 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 m2/g. The FESEM micrograph and elemental analysis showed that desired atomic ratio of the DDR zeolite was obtained after 5 days of synthesis. |
