Preparation and characterization of zeolite beta with low SiO2/Al2O3 ratio

Zeolite beta with a low SiO2/Al2O3 ratio was synthesized by a novel two-step process. The synthesized sample was characterized with XRD, SEM, FTIR, and N2 adsorption-desorption and solid-state MAS NMR. The results showed that aluminium species were inserted into the framework of zeolite beta. The BET surface area, volume, and particle size of the zeolite beta sample decreased with decreasing SiO2/Al2O3 ratio. Our process was proved an efficient route to synthesize zeolite beta with a low SiO2/Al2O3 ratio.
