X 6 Al 2 HT500 hydrotalcites, where X represents Mg, Fe, Cu or Zn were synthetized and investigated before and after gold deposition for toluene and CO total oxidation reactions. The samples have been characterized by specific areas, XRD measurements and Temperature Programmed Reduction. Concerning the toluene total oxidation, the best activity was obtained with Au/Cu 6 Al 2 HT500 catalyst with T 50 at 260 °C. However, catalytic behavior of Au/X 6 Al 2 HT500 sample in both reactions depends mainly on the nature of the support.
