The functionality of solid materials is defined by the type and ordering of the constituent atoms. By introducing defects that perturb the ordered structure, new functionality is created within the solid material. Atomic defects in titanium dioxide, such as oxygen vacancies, atomic hydrogen, and interstitial Ti, typically create new functionality. However, the fundamental physical properties of atomic defects in TiO2 are not fully understood and still remain controversial. In this account, the progress and issues for debate regarding the physical properties, electronic structure, and manipulation mechanisms of atomic defects in TiO2 as well as their interaction with gold nanoclusters are described.
