Nature and degree of distortion of TiO2 (Anatase) surface octahedra upon formation of Ti3+ ions

  • V. I. Zarko


We show that in the transition from Ti(IV) to Ti(III), on the surface of anatase the TiO6/3 octahedra undergo compressive tetragonal distortion. The axial Ti−O bond length in the octahedron decreases in this case by at least 0.0027 nm.
