The activity of combined Co—V/SiO2 oxide catalysts in the ozone-catalytic oxidation (OZCO) of volatile organic compounds (VOCs) using n-butane as a model compound was studied. The two-component Co3O4—V2O5/SiO2 catalysts were shown to be much more efficient in VOCs oxidation at temperatures of 50–150 °C then the one-component Co3O4/SiO2 and V2O5/SiO2 systems. An enhanced efficiency of ozone-catalytic oxidation on the two-component Co3O4—V2O5/SiO2 catalysts can be interpreted to mean that a bifunctional route is operative according to which the ozone decomposition step with the formation of highly reactive atomic oxygen (O*) proceeds on Co sites and the n-C4H10 activation step proceeds on V sites.
