Controlled Crystallization of LTA Zeolitic Nanoparticles from a Clear Solution Using Organic Template

LTA Zeolite nanoparticles was successfully synthesized from clear solution under controlled conditions using hydrothermal method using tetramethyl ammonium hydroxide as a structural directing agent. The as-synthesized LTA zeolite particles were characterized by powder X-ray Diffraction (XRD) analysis, Scanning Electron Microscopy (SEM), Fourier Transform InfraRed (FT-IR) spectroscopy, Energy Dispersive X-ray (EDX) analysis  and surface area measuring technique of Brunauer, Emmett and Teller (BET). XRD patterns and FT-IR spectra were ascertained the formation of pure crystalline phase of ۴A (i.e. LTA) zeolite. SEM micrograph was shown particles size in the range of ۶۰ -۱۷۰ nm with uniform morphology. The Si /Al ratio of the as-synthesized zeolite nanoparticles was ۱.۶۶ with a BET surface area of ۴۲۱ m۲/g.
