摘要： 本文研究了NH4OH-TBAOH体系碱金属离子对硅沸石-2生成时晶型转化、晶胞组成、晶体大小和形貌等方面的影响规律.

Abstract: In contrast with the results previously reported, we have found that Silicalite-2 can be prepared when in the presence of certain amount of alkali metal cations (as chlorides)from NH4OH-TBAOHsystem. Further, our work demonstrated the essential role played by various alkali metal cations during the crystallization of the Silicalite-2 in crystal transformation, the composition per unit cell, the particle size and morphology of the crystallites.
