Anotace	The Ce-Zr mixed oxides, prepared by the sol-gel method, have been examined as supports for platinum and gold in deep oxidation of ethanol and toluene. A weight ratio of Ce/Zr in the synthesized supports was 1/1. Two supported noble metals with a different loading (2.5 and 0.3 wt. %) were compared to each other as well as to selected industrial catalysts (HHC-5557 and VOC-1544). New platinum catalysts showed better activity in oxidation of ethanol and toluene than their gold homologues. Furthermore, they were comparable or even more active than industrial samples (50 % conversion of ethanol was achieved with 2.5Pt/CeZr at 99 °C). On the other hand, gold catalysts proved the best selectivity in oxidation of both model molecules from all tested samples. The additional contributions of present article are the characterizations of catalysts such as XRD, TPR-TPD or FE-SEM.
