摘要：

The oxidic precursor of molybdenum based catalysts supported on stabilized zirconia and on zirconia stabilized titania have been characterized by laser Raman ( LRS) and Fourier transform infrared ( FT-IR) spectroscopy and by. X-ray photoelectron spectroscopy ( XPS). Analysis of the supports by LRS and X-ray diffraction showed that the tetragonal form of zirconia and the anatase form of titania were stabilized. Deposition of oxomolybdate species does not modify the properties of these supports and a monolayer like coverage up to 7 Mo at.nm(-2) and 5 Mo at.mn(-2) was obtained on xirconia and TiO(2)-ZrO(2)-, respectively. Nickel added by impregnation was shown to interact with the supported oxomolybdate species as well as nickel from a ZrO(2)-NiO support.
