11-P-16 - From borosilicate to gallo- and aluminosilicate zeolites: new methods for lattice substitution via post-synthetic treatment

This chapter discusses novel methods for the lattice substitution of heteroatoms in large and extra-large pore borosilicate zeolites through post-synthetic treatment to prepare catalytically more active zeolites. Ga-SSZ-33, A1-SSZ-33, and Al-UTD-1 prepared from B-SSZ-33 and B-UTD-1, respectively, are discussed as examples. The materials are characterized with various physicochemical techniques and catalytic reactions. The advance of these methods is demonstrated by the exceptionally high activity of the resulting A1-SSZ-33 for acid-catalyzed hydrocarbon conversions.
