Dual Templating for AFX/LEV Intergrowth Zeolite

Abstract Zeolite composed of an intergrowth structure based on AFX and LEV framework types was successfully synthesized by dual-templating strategy using 1,1′-(1,4-butanediyl)bis(1-azonia-4-azabicyclo[2,2,2]octane) and dimethylpiperidinium hydroxides. DIFFaX simulation and 13C NMR results indicated that the AFX framework-type is the main component of the intergrowth structure. The intergrowth material obtained was characterized using XRD, SEM, 27Al and 29Si NMR, and N2 adsorption measurements.
