Abstract
The electrochemical behavior of titanium dioxide (TiO 2) 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 TiO 2 shows that Li xTiO 2, Ti 2O 3, Ti 2O and TiO are formed. The formation of Li xTiO 2 is confirmed through X-ray photoelectron spectroscopy (XPS) and Fourier transform infrared spectroscopy (FTIR) studies of the electroreduced TiO 2. The formation of Li xTiO 2 is electro reversible. In this respect, the electrochemical behavior of TiO 2 in concentrated aqueous lithium hydroxide electrolyte is similar to that for lithium perchlorate (LiClO 4) non-aqueous media.
