Chapter Photocatalytic Properties of Commercially Available TiO2 Powders for Pollution Control

---

The photocatalytic properties of titanium dioxide have been widely studied over recent
decades since the discovery of water photolysis by TiO2
electrodes in 1972. Titanium
dioxide has three main crystal polymorphs; anatase, rutile and brookite and rutile is the
most common as the metastable polymorph. Each polymorph has different band gap
positions. Anatase’s band gap is 3.2 eV, higher than rutile’s which is 3.0 eV. This difference
in the band gap will determine their optimum UV wavelength range to promote a
photocatalytic process
