Abstract Details

2004, Master of Science, Miami University, Paper Science and Engineering.
The use of nanostructured V2O5 / TiO2 and WO3 / V2O5 / TiO2 catalysts was investigated for the low temperature oxidation of methanol. A wet incipient method was used to dope WO3 and V2O5 on the Ishihara ST-01 TiO2 support. The V/Ti mass ratios varied from 0 to 0.10 for the V2O5 / TiO2 catalysts, and the W/Ti mass ratios varied from 0 to 0.10 with constant V/Ti mass ratio = 0.02 for the WO3 / V2O5 / TiO2 catalysts. Characterization of the catalysts using X-ray Diffraction, BET surface area and Raman Spectroscopy showed that the thermal stability of catalysts decreased with increasing V/Ti mass ratio over 0.02 but increased with increasing W/Ti mass ratio. The catalytic activity for methanol oxidation increased with W/Ti mass ratio up to W/Ti = 0.05. The catalyst having 0.05 V/Ti mass ratio and calcined at 400 °C showed the highest catalytic activity.
