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 4a (i.e. lta) zeolite.sem micrograph was shown particles size in the range of 60 -170 nm with uniform morphology.the si /al ratio of the as-synthesized zeolite nanoparticles was 1.66 with a bet surface area of 421 m2/g
