Abstract
Sonochemical-assisted method has been identified as one of the potential pre-treatment methods which could reduce the formation duration of zeolite as well as other microporous and mesoporous materials. In the present work, zeolite T was synthesized via sonochemical-assisted pre-treatment prior to hydrothermal growth. The durations for sonochemical-assisted pre-treatment were varied from 30Â min to 90Â min. Meanwhile, the hydrothermal growth durations were ranged from 0.5 to 3Â days. The physicochemical properties of the resulting samples were characterized using XRD, FESEM, FTIR and BET. As verified by XRD, the samples synthesized via hydrothermal growth durations of 1, 2 and 3Â days and sonochemical-assisted pre-treatment durations of 60Â min and 90Â min demonstrated zeolite T structure. The samples which underwent sonochemical-assisted pre-treatment duration of 60Â min yielded higher crystallinity with negligible change of zeolite T morphology. Overall, the lengthy synthesis duration of zeolite T has been successfully reduced from 7Â days to 1Â day by applying sonochemical-assisted pre-treatment of 60Â min, while synthesis duration of 0.5Â days via sonochemical-assisted pre-treatment of 60Â min was not sufficient to produce zeolite T structure.
