Abstract
The study demonstrates the possibility of promoting the V2O5/SiO2 catalyst with a small amount of Co to increase its activity in the ozone-assisted catalytic oxidation (OZCO) of volatile organic compounds. It was found that the conversion of n-C4H10 over the Co-promoted V2O5/SiO2 catalyst (0.5% of Co w/w) at 50–100 °C significantly increases compared to that found over the reference catalysts Co3O4/SiO2 and V2O5/SiO2. This is achieved by increasing the rate of O3 decomposition at Co sites, which enhances the formation of reactive atomic oxygen species O*, and subsequent acceleration of the OZCO process. High efficiency of ozone consumption in the OZCO of n-C4H10 over the Co-promoted V2O5/SiO2 catalyst is due to the involvement of molecular oxygen in the oxidation reaction and to minimization of undesired recombination of the O* species.
