초록
The interest is focused on the control of crystal morphology of single phase zeolite nanocrystals from cube, LTA to octahedron,Faujasite by the mol ratio of TEOS /Al(i-pro)3 in the mother solution, a Al(i-pro)3 : 2.2 TEOS: 2.4-5.7 TMAOH: 0.3 NaOH :200 H2O compositions. Well- controlled single nanocrystals of a high quality zeolite LTA with a size of 264 nm and sodalite with a size of 30-50 nm were synthesized by the compositions having a TEOS /Al(i-pro)3 : 2.2 and 5.2, respectively. The synthesized crystals were characterized by scanning electron microscopy (SEM). high resolution transmission electron microscopy(HRTEM), X-ray powder diffraction(XRD), and dynamic light scattering (DLS).
