57Fe Mossbauer Spectroscopic Study of Fe Redox Centers in Titanium Silicates


EMSL Project ID
1732

Abstract

Novel microporous titanosilicates display unique sorption and catalytic properties and are consequently being intensively studied. For instance TS-1, a member of the MFI topological family, when substituted at the less than one percent level with Ti(IV) becomes a potent epoxidation catalyst. The titanosilicate known as sitinakite (Na2Ti2SiO7.2H2O), on the other hand has been shown to be among the best Cs-selective ion-exchangers while another titanosilicate, ETS-10, sorbs heavy metal ions effectively. The ability to introduce additional redox centers into these materials, in either framework positions and/or in exchangeable cation sites located in the structural channels can significantly affect chemical reactions occurring on the surfaces or within these channels.
