Abstract
The crystal structure, physical, chemical and phase transition properties of trititanium pentoxide (Ti3O5) have aroused a broad range of research effort since the 1950s. Different crystalline forms (α, β, γ, δ and λ) of Ti3O5 exhibit various properties. Particularly, reversible phase transitions between λ- and β-Ti3O5 have been attracting increasing research interest, which brings new potential applications of Ti3O5 materials in the field of energy and data storage. More recently, Ti3O5 materials have shown excellent performance in trace detection, microwave absorption and virus adsorption, which has expanded its application fields. Here, the essential properties of different crystal forms of Ti3O5 are described in detail. An intensive overview of Ti3O5 preparation methods and applications is comprehensively summarized.
