摘要

Titanium sesquioxide (Ti2O3) is drawing broad attention due to its fascinatingphysical properties and promising applications in the fields of energy,biomedicine, and electronics, among others. Its richness is due mainly tothe strongly correlated 3d1 electrons on the Ti~(3+) sites. In stark contrast totitanium dioxide (TiO_2), Ti_2O_3 has an ultra-narrow bandgap (≈0.1 eV) at roomtemperature, resulting from strong correlation among the 3d1 electrons. Distinctelectrical and optical properties are introduced in Ti2O3, accompaniedwith varied intriguing applications. Remarkable photothermal conversion,infrared photodetection, and electrocatalytic properties have been reportedand explored in the past few years. Based on its unique and excellent properties,Ti_2O_3 has been utilized in seawater desalination, electrocatalytic watersplitting, cancer therapy, hydrogen production, mid-infrared photodetection,nitrogen fixation, Li-ion batteries, etc. Herein, the fabrication, structural andelectronic properties of Ti_2O_3 are comprehensively introduced, with a focusedsummary of recent research progress on its applications. Finally, current challenges,opportunities, and future perspectives of Ti_2O_3 are discussed.
