摘要
Titanium containing MCM-41 silica materials, prepared by direct synthesis or wet impregnation technique Were investigated with XRD, TEM, N-2-physisorption. TPR-TG, UV-vis diffuse reflectance and FT-IR spectroscopy. presence of titanium mainly in tetrahedral position was observed for the samples prepared by direct synthesis. while a significant amount of anatase is registered for [lie impregnated one. The former materials possess higher catalytic activity in total toluene oxidation. (C) 2008 Elsevier B.V. All rights reserved.
