Abstract
Titaniumoxide supported MCM-48 was prepared by a novel synthesis method, utilizing titanylacetyl-acetonate as the Ti source. The process consists of an adsorption and subsequent thermolysis of the Ti-complex. The interaction of the complex with the surface was studied by FTIR, TGA and chemical analysis. Further characterization was done by XRD, Raman, UV-DR and N2 adsorption measurements. The Ti-complex is irreversibly adsorbed on the MCM-48 surface by a hydrogen bonding mechanism independent of the Ti loading. During calcination, the supported TiO(acac)2 complex is converted towards supported titaniumoxide, whereby the Ti atoms are partly incorporated into the pore walls of MCM-48. The adsorption of TiO(acac)2 is an efficient way to create supported titaniumoxides with a high surface area.
