Titanosilicate zeolites are synthesized from bulk titania and silica by a newly developed method using mechanochemical reaction. in this method, an amorphous silica-titania composite is prepared by grinding titania and silica powders with a planetary ball mill and converted into a titanosilicate zeolite through the succeeding hydrothermal treatment. Ti atoms from bulk titania are dispersedly incorporated into the zeolite framework as a tetrahedrally-coordinated species, which is evidenced by several characterization results. By using this new synthesis method, a TS-1 material is obtained highly reproducibly from inexpensive bulk materials without practiced manipulation. (c) 2006 Elsevier Inc. All rights reserved.
