The Formation and Detection Techniques of Oxygen Vacancies in Titanium Oxide-based Nanostructures

Abstract

TiO2 and other titanium oxide-based nanomaterials have drawn the immense attention of the researchers from different domains of science for their fascinating multifunctional properties, relative abundance, environmental friendliness, and bio-compatibility. However, the physical and chemical properties of the titanium oxide-based nanomaterials are found to be explicitly dependent on the presence of various crystalline defects. Oxygen vacancies are the most frequent and foremost among them and always been the subjects of both theoretical and experimental research as they play crucial role in tuning the inherent properties of titanium oxides. This review highlights the different effective strategies for introducing oxygen vacancies in the titanium oxide-based nanomaterials and a discussion has also been made on the positions of oxygen vacancies inside the TiO2 band gap, based on the theoretical calculations. Along with these, a detail review on the different experimental techniques have also been presented here, which are extensively used for identifying the oxygen vacancies in the TiO2 nanostructures.
