Abstract

The preparation and characterization of a cobalt substituted ETS-10 titanosilicate are described. X-ray diffraction shows that cobalt incorporation causes an increase in unit cell dimensions. UV-VIS, EPR, Raman and Co K-edge C XANES spectra all show that Co2+ occupies tetrahedral sites, substituting for silicon. The Si-29 NMR spectra do not permit identification of which silicon sites in ETS-10 are substituted, but the Co K-edge EXAFS shows clearly that Co2+ substitutes at Si(3Si,1Ti) sites.
