| 英文摘要 | zsm-2 nanorods with crystal size around 50 nm were successfully synthesized at ambient temperature (30 degrees c). the crystallization process of zsm-2 zeolite under ambient temperature was studied and discussed according to the measurement of crystallization kinetic curve, and characterizations with multiple techniques, such as x-ray diffraction (xrd), scanning electron microscopy (sem), low-temperature n-2 adsorption/desorption analysis, thermogravimetry analysis (tg) and nuclear magnetic resonance (nmr) etc. the zsm-2 zeolite synthesized at ambient temperature presented different crystal morphologies and large specific area as compared with the sample synthesized at high temperature (100 degrees c). furthermore, si-29 mas-nmr showed that the nanoscale zsm-2 obtained by ambient synthesis contained more emt phase and lower si/al ratio than that of micrometer-sized zsm-2 crystals obtained at 100 degrees c. more interestingly, nmr and low-temperature n-2 adsorption/desorption characterizations revealed that the local environment of al did not change much while that of si did change a lot during the ambient crystallization process, and the micropore area increased rapidly while the micropore size distributions of the samples changed little with increasing crystallization time.
