zeolite和molecular sieve的區(qū)別
|
|||
|
如題,二者有什么區(qū)別呢?這是文獻上的一段,大家看看是什么意思?? (2) In comparison with zeolites, mesostructured materials show much faster formation rates. It takes only several seconds to minutes for the crystallization as solid precipitation. The crystallization of zeolites generally requires several days and even months. (3) Mesoporous molecular sieves can be formed in nonaqueous media. In many polar organic solvents, like alcohols and tetrahydrofuran (THF), mesostructures can be formed through solvent evaporation induced self-assembly (EISA) or the solvothermal synthesis method. Water is however, necessary in the preparation of zeolites. Without water, zeolites cannot be fully crystal-lized. |
