摘要
Catalysts V2O5/TiO2-carbon nanotubes (CNTs) were prepared by hydrothermal method and their activity for catalytic oxidation of chlorobenzene (CB) was studied. A CB conversion efficiency of 45% with a CO2 selectivity of 80% was achieved over V2O5 (1.2 wt 96)/TiO2-CNTs(8.6 wt 96) at a temperature as low as 200 C. It also has the highest removal efficiency of 95% at 300 degrees C. From the analysis of XRD, SEM, TEM, and TPR, the low-temperature activity of V2O5/TiO2-CNTs could be ascribed to the high S-BET, good dispersion of V2O5, and the possible adsorption of CB by free surface of CNTs.
