Preparation of titanium oxide supported MCM-48 by the designed dispersion of titanylacetylacetonate

Titaniumoxide supported MCM-48 was prepared by a novel synthesis method, ut ilizing titanylacetyl-acetonate as the Ti source. The process consists of a n adsorption and subsequent thermolysis of the Ti-complex. The interaction of the complex with the surface was studied by FTIR, TGA and chemical analy sis. Further characterization was done by XRD, Raman, UV-DR and N-2 adsorpt ion measurements. The Ti-complex is irreversibly adsorbed on the MCM-48 sur face by a hydrogen bonding mechanism independent of the Ti loading. During calcination, the supported TiO(acac)(2) complex is converted towards suppor ted titaniumoxide, whereby the Ti atoms are partly incorporated into the po re walls of MCM-48. The adsorption of TiO(acac)(2) is an efficient way to c reate supported titaniumoxides with a high surface area.
