Abstract

Fluorine modified oxide surfaces have received considerable attention both as research materials and as commercial catalysts. Pulsed NMR has been used to directly observe protons and fluorine on fluorine modified silica,alumina, and aluminosilicates. The center of mass of the 19F spectra is consistent with values reported for covalent siliconfluorine and aluminum-fluorine bonds. The proton and fluorine concentrations have been investigated as a function of sample preparation.
