A new method has been developed to prepare sulfated zirconia (S-ZrO 2 ) supported on mesoporous silica. With direct exchange of metal containing precursors for the surfactants in the as-synthesized MCM-41 materials, the problem of fill-up of the mesoporous structure was avoided and high sulfur content was achieved. By using this method, the composite of S-ZrO 2 /MCM-41 with ZrO ...
