Abstract
This study examined the catalytic oxidation of 1,2-dichlorobenzene on V2O5/TiO2 nanoparticles. The V2O5/TiO2 nanoparticles were synthesized by the thermal decomposition of vanadium oxytripropoxide and titanium tetraisopropoxide. The effects of the synthesis conditions, such as the synthesis temperature and precursor heating temperature, were investigated. The specific surface areas of V2O5/TiO2 nanoparticles increased with increasing synthesis temperature and decreasing precursor heating temperature. The catalytic oxidation rate of the V2O5/TiO2 catalyst formed by thermal decomposition process at a catalytic reaction temperature of 150 and 200 C was 46% and 95%, respectively. As a result, it was concluded that the V2O5/TiO2 catalysts synthesized by a thermal decomposition process showed good performance for 1,2-DCB decomposition at a lower temperature.
