Metallic mixed oxides (Pt, Mn or Cr) as catalysts for the gas-phase toluene oxidation

The gas-phase toluene oxidation was studied over metal containing mixed oxides derived from hydrotalcite-like compounds with high specific surface area. Both the catalysts with platinum and manganese showed to be promising catalysts, due to its good activity and low light-off temperature. Special attention must be paid to the platinum catalyst, which showed a light-off at 460 K and complete toluene oxidation at 635 K. No other products besides CO2, CO and H2O were observed.
