Abstract
The influence of phosphates on the surface characterization of TiO2Al2O3 mixed oxides was investigated using a variety of techniques, such as nitrogen adsorption, TEM, XRD, XPS, and FT-IR. The XRD and XPS results indicate that the addition of phosphates can increase the dispersion of titanium component on the surface of alumina. And smaller TiO2 clusters can be observed by TEM. The FT-IR patterns show that the samples modified by the presence of phosphates possess more adsorption-active sites, and a larger monolayer dispersion capacity for TiO2, which accounts for the increased dispersion of TiO2 on the surface of the Al2O3.
