Title:
Evidence for F-/SiO- anion exchange in the framework of As-synthesized all-silica zeolites
Authors:
Liu, Xiaolong; Ravon, Ugo; Tuel, Alain
Abstract:
Not everything changes: 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 (see picture). Fluoride removal is not possible in all-silica D4R units, for which fluoride ions play a structure-directing role. © 2011 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
