Open publisher page 0 citations

Abstract

The nanosized composite microporous molecular sieve(A/X) was quickly synthesized under ultrasonic irradiation for 20 min at 60 ℃ without template,and characterized by XRD,BET,TEM and FTIR techniques.BET results show that the external surface area and microporous area are 121.14 m2/g and 257.70 m2/g,respectively.From the TEM characterization,it can be seen that the as-synthesized composite zeolite is spherical with uniform particle size of about 10 nm.The results indicate that the sample has ordered pore structure,perfect framework,small size and good dispersibility.
