A highly ordered 2D-hexagonal mesoporous titanium silicate synthesized under moderately basic condition by using a modified synthesis procedure in the presence of a non-ionic surfactant dodecylamine (DDA) as the structure-directing agent (SDA) has been reported. This mesoporous material was characterized by using powder XRD, N-2 adsorption/desorption, TEM, SEM-EDS and spectroscopic studies. UV-vis and Si-29 MAS NMR studies suggested the incorporation of isolated tetrahedral Ti(IV) sites in a highly cross-linked silica framework. N-2 sorption analysis revealed good surface area and narrow pore size distribution. This mesoporous titanium silicate efficiently catalyzed the epoxidation of acrylic acid in acetonitrile solvent in the presence of H2O2 as oxidant with high-yield and excellent selectivity. Oxidation of styrene over this mesoporous titanium silicate has also been studied. (C) 2007 Elsevier B.V. All rights reserved.
