Titanium sesquioxide (Ti2O3) is drawing broad attention due to its fascinating physical properties and promising applications in the fields of energy, biomedicine, and electronics, among others. Its richness is due mainly to the strongly correlated 3d1 electrons on the Ti3+ sites. In stark contrast to titanium dioxide (TiO2), Ti2O3 has an ultra-narrow bandgap (≈0.1 eV) at room temperature, resulting from strong correlation among the 3d1 electrons. Distinct electrical and optical properties are introduced in Ti2O3, accompanied with varied intriguing applications. Remarkable photothermal conversion, infrared photodetection, and electrocatalytic properties have been reported and explored in the past few years. Based on its unique and excellent properties, Ti2O3 has been utilized in seawater desalination, electrocatalytic water splitting, cancer therapy, hydrogen production, mid-infrared photodetection, nitrogen fixation, Li-ion batteries, etc. Herein, the fabrication, structural and electronic properties of Ti2O3 are comprehensively introduced, with a focused summary of recent research progress on its applications. Finally, current challenges, opportunities, and future perspectives of Ti2O3 are discussed.

三氧化二钛的最新进展：制备、性能和应用
三氧化二钛 (Ti 2 O 3 ) 因其迷人的物理特性和在能源、生物医学和电子等领域的广阔应用前景而受到广泛关注。它的丰富性主要是由于Ti 3+位点上的强相关3 d 1电子。与二氧化钛（TiO 2）形成鲜明对比的是，Ti 2 O 3在室温下具有超窄带隙（≈0.1 eV），这是由于 3 d 1电子之间的强相关性所致。Ti 2 O 3中引入了不同的电学和光学特性，伴随着各种有趣的应用程序。在过去的几年中，已经报道和探索了显着的光热转换、红外光电探测和电催化性能。Ti 2 O 3基于其独特而优异的性能，已被应用于海水淡化、电催化水分解、癌症治疗、制氢、中红外光电探测、固氮、锂离子电池等领域。全面介绍了Ti 2 O 3的电子特性和电子特性，重点总结了其应用的近期研究进展。最后，Ti 2 O 3当前的挑战、机遇和未来前景被讨论。
