Abstract
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 Li x TiO2, Ti2O3, Ti2O and TiO are formed. The formation of Li x TiO2 is confirmed through X-ray photoelectron spectroscopy (XPS) and Fourier transform infrared spectroscopy (FTIR) studies of the electroreduced TiO2. The formation of Li x TiO2 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.
