The electrochemistry of solute species in ionic liquids is investigated by use of cyclic voltammetry. The cyclic voltammetry of transition metals of varying oxidation states are presented as well as the electrochemistry of uranium as both a solute and a metallic electrode in a variety of ionic liquids and comparisons are made between their behaviour. Transport properties of the solute species have been determined by the use of an electrochemical technique known as chronocoulometry. This involves the application of a potential step and the subsequent observation of the charge passed as a function of time to determine the diffusion coefficient of the solute. Diffusion data is collection at a variety of temperatures in order to obtain an Arrhenius plot, and thus obtain activation energies for diffusion for each solute species, and data have been compared and contrasted for the ionic liquids and solutes employed. Structural analysis of the ionic liquids has also been performed by utilising single crystal x-ray crystallography to study the interaction between both the anion and cation of the ionic liquid, and between solute species and the anion and cation of the ionic liquid. The crystal structure of 1-ethyl-3-methylimidazolium chloride that offers a significant improvement over previously published data is presented along with the crystal structure of a new ionic liquid, 1-ethyl-3-methylimidazolium dichloroargentate. Powder x-ray diffraction and Raman spectroscopy data are also presented as part of the structural analysis of these ionic liquid systems.
