摘要: Low-silica zeolite L (zeolite GL) syntheses in the presence of emulsions were investigated. High aspect ratio rods obtained when LTL was crystallized both cationic and nonionic two-phase emulsions. Conventional primarily led to low crystals possessing a length/width approximately 1.5. In emulsion ratios increased with most samples between 5 10, although observed as high 42. TEM analysis indicates pores are parallel long axis crystals. It is that anisotropic formed surfactant (CTAB) cation below 3.5. By contrast CTAB/(Ba2++K+) greater than four phase does not form. Igepal CO-720 also used determine if similar could be While rods, purity t...
