On the basis of titano-siliceous ethers (BuO)2Ti[OSi(OtBu)3]2 and BuOTi[OSi(OtBu)3]3 as molecular precursors, the mesoporous titanosilica materials with high content of titanium (the Ti/Si up to 0.36) and high sorption characteristics are prepared by template synthesis in presence of micell-forming surfac- tants. It is shown that the features of the prepared mesoporous and mesostructured matrices consists in considerable thickness of mesopore walls (2-4 nm), which is probably the result of using bulky titano-siliceous «bilding blocks» in template synthesis.
Key words: template synthesis, titano-siliceous ethers, titanosilica.
