Abstract
An EXAFS multishell analysis of a titanium silicalite with an MFI stru cture reveals that the double Si-O-Ti bridges formed between [TiO(x)] species and the [SiO4] framework tetrahedra are partially hydrolysed i n the presence of water which results in the conversion from an edge- to a corner-sharing type of bonding between the two structural units.
