Abstract
Using acetylacetone as the hydrolysis-retarding agent, titanium has been directly incorporated into mesoporous silica thin films by a dip-coating method for the first time. Evidence from the ultraviolet-visible (UV-Vis) absorbance spectra, high-resolution electron microscopy (HREM), energy dispersion spectrum (EDS) and electron probe X-ray microanalysis (EPMA) indicated that Ti atoms were homogeneously dispersed in the siliceous framework and existed in the form of a Ti-O-Si bond. The increase of the film's basal spacing accompanied with an increase of Ti content was also observed.
