Considerable attention has been paid to reduced transition metal nanomaterials because they exhibit attractive properties for practical applications in fuel cells, memory or thermoelectric devices, and photocatalysts. In particular, a series of oxygen-nonstoichiometric titanium oxides has advantages such as abundance of the elements, non-toxicity, corrosion resistance, and high electrical conductivity. However, the control of nanostructures is not straightforward because a high-temperature reductive condition is required for the synthesis of highly reduced metal oxides. Recently, it has been demonstrated that the novel low-temperature reduction technique can afford highly reduced titania nanoparticles with different particle sizes ranging from 20 to 300 nm diameter. This review article is focused on the synthesis of corundum-type Ti2O3 nanoparticles, the reaction mechanism, and the correlation between structure and physical properties.
