| 1. | It is discovered that existence of small amount of n - butyl alcohol in mesoporous zeolite synthesis system can not only modify ordered degree of formation of mesoporous zeolite , which improves hydrothermal stability of it , but also help to attain much smaller , nearly nanometer , grain of mesoporous zeolite 研究发现,少量正丁醇的存在能改善介孔分子筛形成过程的有序度,并使其水热稳定性得到提高,同时合成产物的粒度更小,趋近纳米颗粒。 |
