      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
                      defects. Moreover, we provide important information on the
                      nucleation, growth, and crystallization processes during
                      synthesis, emphasizing the impact of Fe atom incorporation
                      on the TiO$_2$ lattice, the formation of reaction
                      intermediates, and the structural evolution at the nano
                      regime. The ability to control oxygen vacancies and engineer
                      defects in Fe-doped TiO$_2$ allows for the optimization of
                      charge transport, enhancing catalytic activity and tuning
                      optical properties for applications in environmental
                      remediation, sensing, and next-generation semiconductor
