摘要：
dIn the paper, we review the preparation and the characterization of CrOx/ZrO2, MoOx/ZrO2 and VOx/ZrO2. Catalysts were prepared by various methods (equilibrium adsorption, impregnation or mechanical mixing) and characterized by XRD, XPS, ESR and FTIR techniques. In the paper, we also review the catalytic activity of the ZrO2 supported systems for propene hydrogenation (CrOx/ZrO2 and MoOx/ZrO2), propane or isobutane dehydrogenation (CrOx/ZrO2), abatement of NO with H-2, propane, or propene (CrOx/ZrO2), abatement of NO with NH3 (VOx/ZrO2). In selected cases, in order to assess the influence of the support on the catalytic activity, we compare the activity of the MeOx/ZrO2 samples with that of the same MeOx, on other supports.
