摘要：

Titanium silicalites with different titanium contents were synthesized according to two hydrothermal procedures. The materials were subjected to physicochemical characterization and tested as catalysts for partial oxygenations by aqueous hydrogen peroxide. The role of isolated titanium, finely divided titanium dioxide and residual acidity in the catalytic behavior of titanium silicalites is discussed and a mechanistic model for the oxidation reactions is proposed.
