Catalytic oxidation of chlorobenzene over V2O5/TiO2–carbon nanotubes composites / Anmin Nie in Industrial & engineering chemistry research, Vol. 50 N° 17 (Septembre 2011)

A CB conversion efficiency of 45% with a CO2 selectivity of 80% was achieved over V2O5 (1.2 wt %)/TiO2-CNTs(8.6 wt %) at a temperature as low as 200 °C. It also has the highest removal efficiency of 95% at 300 °C. From the analysis of XRD, SEM, TEM, and TPR, the low-temperature activity of V2O5/TiO2-CNTs could be ascribed to the high SBET, good dispersion of V2O5, and the possible adsorption of CB by free surface of CNTs.
