Doping of TiO2 Polymorphs for Altered Optical and Photocatalytic Properties

Figure 1

Composite phase diagram for TiO2. The anatase/TiO2-II, anatase/rutile, and TiO2-II/rutile phase boundaries are taken from Ren et al. [71]. The TiO2-II/rutile phase boundary at high temperatures and pressures is taken from Withers et al. [58]. The filled point shows the 0 K anatase-to-brookite transition pressure estimated by Beltrán et al. [32].
