The TiO2 support materials were synthesized by a chemical vapor condensation (CVC) method and the subsequent MnOx/TiO2 catalysts were prepared by an impregnation method. Catalytic oxidation of toluene on the MnOx/TiO2 catalysts was examined with ozone. These catalysts had a smaller particle size (9.1 nm) and a higher surface area (299.5 m(2) g(-1)) compared to MnOx/P25-TiO2 catalysts. The catalysts show high catalytic activity with the ozone oxidation of toluene even at low temperature. As a result, the synthesized support material by the CVC method gave more active catalyst.
