High-temperature stabilized anatase TiO2 from an aluminum-doped TiCl3 precursor

The solid-state hydrolysis and air calcination of aluminum-doped TiCl3 leads to crystalline anatase TiO2 that is stable on heating to 1000 °C, in contrast to control studies with related AlCl3 and TiCl3 physical mixtures that produce rutile TiO2 under the same conditions.
