Plus de détailsThe density functional calculations allow for a consistent understanding of all three phases. In the rutile phase metallic conductivity is carried by metal orbitals, which fall into the one-dimensional band, and the isotropically dispersing bands. Hybridization of both types of bands is weak.
Plus de détailsTitanium dioxide, TiO2, is an important photocatalytic material that exists as two main polymorphs, anatase and rutile. The presence of either or both of these phases impacts on the photocatalytic performance of the material. The present work reviews the anatase to rutile phase transformation. The synthesis and properties of anatase and rutile are examined, followed by a …

Plus de détailsRutile-TiO 2 has a relatively smaller energy bandgap (E G = 3 eV) than 3.2 eV of Anatase-TiO 2. And thus, more electrons can be generated in the conduction band of Rutile-TiO 2, resulting in the enhanced photocurrent value from the Anatase-TiO 2 TSC (as shown in Fig. 5a). This strongly suggests the further improvement is possible for ...
