The first materials discovered which belong to this novel group of titanosilicates, having numerous sixfold-coordinated Ti sites in a microporous crystalline array, was ETS-4, which is an analogue of the mineral zorite while the other, ETS-10, is topologically comparable to zeolite (1 [96],...

The best systems for this reaction are based on Au nanoparticles supported either over Ti02 (anatase), or over microporous or mesoporous Ti-silicates (TS-1, Ti-MCM41, Ti-p, Ti-Si02, Ti-TUD, silylated titanosilicate). The pioneer in this field was Haruta [36] many studies concerning novel procedures for the preparation of Au-based systems have since been reported in the literature, including various types of supports [37a,l] and the use of other metal active components, for example, Ag, Pd or Pt [26c, 37m,nj. 

Advances made in the area of mechanism have been presented so as to give a perspective on similarities and differences between different catalysts. Both classical and novel systems have been covered with considerable attention placed on comparisons. Less detail is given for certain homogeneous and heterogeneous catalyst systems reported elsewhere in this book, such as Au/titanosilicates. 

The majority of important synthetic novel zeolites, however, have not been prepared as crystals either large enough or sufficiently well ordered to be studied by available single crystal methods. Zeolites such as Beta, ZSM-12, NU-87, MCM-22 and ITQ-21, and related microporous solids such as the titanosilicate ETS-10, for example, were solved from X-ray powder diffraction and other methods (such as electron microscopy and computer simulations) rather than by single crystal diffraction.
