摘要：

Fluorescence X-ray absorption experiments were carried out on titanium containing zeolites. The edge- and EXAFS-regions proved that the coordination of the Ti-sites of TS-1 and [Ti]ZSM-5 are similar, although no quantitative data could be obtained for the coordination numbers. EXAFS analysis of a [Li, Ti]Y zeolite, containing 12% Ti, showed that most of the titanium has a rutile-like coordination and therefore is not likely to be present as part of the framework.
