On the oxidation state of titanium in titanium dioxide [PDF]
J. Phys. Chem. Lett., 2017, 8, pp 1593-1598, 2017 The oxidation state of titanium in titanium dioxide is commonly assumed to be +4. This assumption is used ubiquitously to rationalize phenomena observed with TiO2. We present a comprehensive electronic structure investigation of Ti ions, TiO2 molecules and TiO2 bulk crystals, using different density functional theory and wave function-based approaches,
