摘要：

Lanthanum-modified TiO2 nanotube (NT) supported gold catalysts were prepared. The linear relationship between actual and nominal lanthanum concentrations was found. The possible formation mechanism of La-modified TiO2 NTs was suggested. The effects of calcination temperature, La concentration and gold loading on the catalytic activity for CO oxidation were investigated. Au/La2O3-TiO2NTs (Au: 4.18%, La: 1.62%) calcined at 300 degrees C could completely convert CO at 30 degrees C. T-100% of La-free catalyst was 60 degrees C. The catalytic activity of Au/TiO2-NTs could be improved by modification with lanthanum.
