The principal objective of research in this group is the elucidation of the mechanisms of complex, multi-step electrode reactions of organic and organometallic compounds. The results of this research are relevant not only in the areas of organic and inorganic chemistry, but also find applications in chemical analysis, electroorganic synthesis, pollution control, electrocatalysis, batteries and fuels cells. A full understanding of an electrode reactions must include a complete description of its component steps. Thus, our work includes studies of the factors controlling the rates of simple electron-transfer reactions occurring at electrode surfaces as well as the electron-transfer reactions in solution near the electrode that involve the various species in the overall mechanism (reactants, intermediates, products). Other component reactions are of a more chemical nature. They may be as simple as an isomerization or conformational change of the reactant or an intermediate. However, bonds may also be formed (dimerization, protonation) or broken (loss of an atom or functional group) and these steps combine with the electron-transfer reactions to make up the overall process. An important type of reaction is bond cleavage associated with electron transfer to or from the reactant. Most such reactions are two-step processes in which an intermediate radical anion is formed followed by expulsion of a leaving group. However, others appear to be concerted processes (dissociative electron-transfer reactions) in which both steps occur together and no intermediate radical ion exists. Part of our research is directed toward discovering new examples of the rarer type, dissociative electron transfers.

In an electrochemical reaction, the chemical species are related by kinetic equations, both chemical... and electrochemical (the rate of which may involve variables such as the applied voltage)... The 'movement' of the species due to Diffusion, flow etc. (known as 'Mass Transport') may also be described mathematically by a partial differential equation for each species. These equations cannot be solved analytically except for extremely simple cases, but they can be solved numerically (using a finite difference method - where the cell is covered in a mesh of points so that the derivatives can be approximated as differences between points). By applying boundary conditions at the edges of the grid, the resulting set of simultaneous equations can be solved by an algorithm such as the Strongly Implicit Procedure. The result of solving all the equations with a computer is a concentration profile for each species - describing the spatial concentration distribution of that species within the electrochemical cell. The concentration profile above shows a microband electrode at steady-state in a channel flow-cell. The colour scale represents reactant concentration (pink = bulk concentration, blue = zero concentration)
