Effect of Lanthana as a Stabilizing Agent in Titanium Dioxide Support

The thermal stability of between 1 and 5 wt % lanthana-doped TiO2 was investigated. Three methods of aging the titania support were studied: stagnant air heating for 12 h at temperatures ranging from 450 to 900 °C, flowing humid 450 °C air for up to 25 days, and flowing humid 650 °C air for up to 3...
