In this study, titanate nanotubes were synthesized by hydrothermal method and impregnated with different percentages (1, 3, and 5% by weight) of vanadium-molybdenum oxides. The X-ray diffraction spectrum obtained from the catalysts confirmed titanate nanotubes formation and specified that it has resulted as anatase mono phase. Titanate nanotubes with high specific surface area of 404 𝑚2 𝑔-1 were obtained from P25 raw material (with low specific surface area of 52 𝑚2 𝑔-1) and specific surface area of synthesized catalysts were also significant, approximately 130-163 𝑚2 𝑔-1. The calcined catalysts (at 400oC in air atmosphere) was studied in fixed bed reactor for 1000 ppm trichloroethylene (TCE) oxidation in air. 1 wt% vanadium-molybdenum catalyst supported on titanate nanotube has a better activation in comparison with other catalysts.
