Photocatalytic Degradation of Organic Dyes Using Titanium Dioxide (TiO2) and Mg-TiO2 Nanoparticles

Abstract

Titanium oxide (TiO2), or titania, is a very important semiconducting material that has attracted great interests due to its unique physical and chemical properties. TiO2 exists in three major crystalline phases, namely, anatase, rutile and brookite. Out of these three, the brookite phase is not practically beneficial because it is stable only at low temperatures. On the other hand, relatively high chemical inertness of the rutile phase makes it a suitable choice in applications where stability is critical.
