Abstract
The catalytic oxidation of 1,2-dichlorobenzene (1,2-DCB) on vanadium oxide supported on titanium oxides (V2O5/TiO2) was investigated. The TiO2 particles used as a support material on the V2O5/TiO2 catalysts were synthesized by chemical vapor condensation (CVC) using a tubular electric furnace at various synthesis temperatures (700–1100 °C) and titanium tetraisopropoxide (TTIP) heating temperatures (80–110 °C). V2O5 containing samples were prepared by impregnating TiO2 with an aqueous solution containing an appropriate amount of ammonium metavanadate. Brunauer–Emmett–Teller (BET) measurements indicated no change in the specific surface area (SSA) of the V2O5/TiO2, whose support material was commercial TiO2 (P25, Degussa), after vanadium impregnation. The SSAs of the V2O5/TiO2 catalysts, whose support material was prepared using the CVC method, increased drastically after vanadium impregnation. XPS showed that the surface vanadium oxide was composed of V2O4 and V2O5. In particular, V5+ species were dominant on the CVCprepared V2O5/TiO2 catalysts. The catalytic oxidation of 1,2-DCB on the CVC-prepared V2O5/TiO2 catalysts showed good performance at lower temperatures.
