Abstract
A series of titanium silicalites of MFI structure, active in n-hexane oxyfunctionalization was investigated by XANES and EXAFS. A multiple s cattering EXAFS analysis has been performed using the FEFF6 code. Tita nium atoms are sited in substitutional framework sites of T-d symmetry , with a large Ti-O-Si angle (approximate to 160 degrees). At high Ti content, extra framework anatase TiO2 is formed.
