Abstract

Zeolite SUZ-4 was successfully synthesized with TEAOH (Tetraethyl ammonium hydroxide) as structure directing agent under a vigorous stirring condition. Well-defined zeolite SUZ-4 structure was only obtained under stirring of 250 rpm or more. The results imply that stirring plays a pivotal role for reproducible synthesis. Morphology of SUZ-4 crystal was controlled by adjustment of water concentrations. The physicochemical characterization of SUZ- 4 and its hydrothermal stability using a steam treatment were investigated by using XRD, BET, and NH3-TPD.
