Abstract

This study examined the catalytic destruction of 1,2-dichlorobenzene on ${V_2}{O_5}/TiO_2$ nanoparticles. The ${V_2}{O_5}/TiO_2$ nanoparticles were synthesized by the thermal decomposition of vanadium oxytripropoxide and titanium. The effects of the synthesis conditions, such as the synthesis temperature and precursor heating temperature, were investigated. The specific surface areas of ${V_2}{O_5}/TiO_2$ nanoparticles increased with increasing synthesis temperature and decreasing precursor heating temperature. In addition, the removal efficiency of 1,2-dichlorobenzene was promoted by a decrease in heating temperature. However, the removal efficiency of 1,2-dichlorobenzene was decreased by an anatase to rutile phase transformation at temperatures $1,300^{\circ}C$.
