| 英文摘要 | nanosized zsm-5 zeolite was synthesized by hydrothermal method and characterized by xrd and tem techniques. the specific heat of the nanosized zsm-5 zeolite was measured in the temperature range from 79 to 370 k, and its enhancement in specific heat was observed as compared with the corresponding microsized zeolite, indicating that the nanosized zsm-5 zeolite possesses higher surface activity. the thermostability of the samples was determined by differential scanning calorimetric (dsc) and thermogravimetric (tg) techniques. the dsc results showed that, for the nanosized zsm-5, a broad exothermic peak is observed from 1300 k; for the microsized zsm-5, the corresponding exothermic peak begins at 1400 k, and a distinct phase transition can be observed at 1620 k. the tg results showed that, for the nanozised zsm-5, the maximum mass-loss ratio is 6.9%, and two mass-loss stages can be observed in the temperature ranges of 298 similar to 663 k and 923 similar to 1273 k, respectively; for the microsized zsm-5, the maximum mass-loss ratio is 6.5% and it is more stable than the nanosized zsm-5. |
