Abstract
Tungsten-ceria catalysts were prepared by co-precipitation and impregnation techniques looking for the effect of the tungsten loading and calcination temperature. The catalysts were characterized by adsorption-desorption isotherms of N-2 at 77 K, in-situ XRD, NH3-DRIFT, Raman spectroscopy, and XPS. It was found that the preparation method influences the texture of the catalyst, the tungsten loading, the dispersion of the WO, domains which correspond to a different interaction with ceria, and the temperature of formation of the Ce-2(WO4)(3) species which seem to be responsible for the strong Lewis/Bronsted acid sites.
