The electrochemical behavior of titanium dioxide (TiO2) in aqueous lithium hydroxide (LiOH) electrolyte has been investigated. Cyclic voltammetry shows that electroreduction results in the formation of a number of products. X-ray diffraction of the electroreduced TiO2 shows that LixTiO2, Ti2O3, Ti2O and TiO are formed. The formation of LixTiO2 is confirmed through X-ray photoelectron spectroscopy (XPS) and Fourier transform infrared spectroscopy (FTIR) studies of the electroreduced TiO2. The formation of LixTiO2 is electro reversible. In this respect, the electrochemical behavior of TiO2 in concentrated aqueous lithium hydroxide electrolyte is similar to that for lithium perchlorate (LiClO4) non-aqueous media.
