A new method has been developed for the preparation of sulfated titania (S-TiO{sub 2}) supported on mesoporous silica. The use of direct exchange of metal containing precursors for the surfactants in the as-synthesized MCM-41 substrate produced a product with high sulfur content without serious blockage of the pore structure of MCM-41. The pore sizes and volumes of the resultant S-TiO{sub 2}/MCM-41 composites were found to vary markedly with the loading of TiO{sub 2}. The strong acidic character of the composites obtained was examined by using them as catalysts for the esterification of acetic acid and n-butanol. - Abstract: XRD profiles of the composites of S-TiO{sub 2}/MCM-41 with different TiO{sub 2} contents. The low angle peaks indicate the MCM-41-like structure retained and a TiO{sub 2} phase appeared at high angle region. Display Omitted
