Theoretical and Experimental Electrochemistry

Our group is interested in both theoretical and experimental aspects of electrochemistry. Much of our current research is focused on electrochemistry at the micro- and nanoscale in order to understand practical chemical, physical, materials, and biologically related problems. Our work includes a focus on the design of novel micro- and nanoelectrodes of various geometries and investigations of their transport properties. We use such electrodes to study the kinetics and mechanisms of electrode reactions using steady-state and transient voltammetries and scanning electrochemical microscopy (SECM). We also use these electrodes and techniques to investigate the transport of ions through thin films and across the openings of nanochannels and nanopores. We are also working on the fabrication and various applications of novel addressable microelectrode arrays. Additionally, we are looking at non-platinum metal nanoparticles and the nanoscale design of catalysts for oxygen reduction and hydrogen oxidation. We use the scanning and positioning capabilities of scanning electrochemical microscopy (SECM) to carry out many of these investigations.
