Oxygen Vacancy-Induced Phase Transformations of Iron-Doped Titanium Oxide Nanostructures.

ABSTRACT: Oxygen vacancies play a pivotal role in tailoring the electronic, optical, and catalytic properties of reducible metal oxides. Here, we provide a complete overview of oxygen vacancy-induced structural evolution of iron-doped titanium oxide nanomaterials with insights into their synthesis, formation, and crystallization processes. Structural analysis combining multiple techniques reveals the formation of anatase nanoparticles at low Fe loadings (i.e., ≤10 at. % Fe). At intermediate Fe concentrations (i.e., 15-20 at. % Fe), a mixture of anatase and rutile forms with the presence of extended disordered defects similar to crystallographic shear planes. These become more notable at high Fe loadings (i.e., ≥30 at. % Fe) with the complete transition to the rutile phase with a high density of defe
