Evidence for F¯/SiO¯ anion exchange in the framework of As-synthesized all-silica zeolites

Keywords

Synthesized zeolite

Abstract

​Charge-compensating anions can be exchanged in as-synthesized zeolite frameworks with changes in both the density of defect sites and of the hydrophobic character of the zeolite. The reversible transformation occurs without dissolution/recrystallization of the zeolite and preserves the size and shape of the crystals. Fluoride removal is not possible in all-silica D4R units, for which fluoride ions play a structure-directing role.
