Abstract: The nanometer HS zeolite was synthesized from the clear solution methed. The product was charactered by XRD and HRTEM, and the growth mechanism was discussed. The results obtained show that nanoparticles of HS zeolite consist of decades of same-size nanocrystals and the growth mechanism is u growth by aggregation".

Key words: zeolite, nanomaterial, synthesis, HRTEM
