Analytical chemistry and electrochemistry
Our group works on the application of electrochemical methods to chemical problems. We are particularly interested in using electrochemistry to elucidate the behavior and properties of novel organic and inorganic species and to study systems under extreme conditions (e.g., in supercritical fluids). We also study the interaction of light and electrochemical systems. For example, one can produce light by electrochemical generation of reactive species (electrogenerated chemiluminescence); this forms the basis of a very sensitive and selective method of analysis. We are also working on the utilization of light in photoelectrochemical cells with semiconductor electrodes or particles for the generation of electricity and chemicals. Fundamental studies of the semiconductor/solution interface and of very small (Q- or quantum-sized) particles are carried out. We have been using scanning probe techniques, like scanning tunneling and atomic force microscopies, to investigate reactions on the surfaces of electrodes with very high (atomic) resolution. We also have been developing the technique of scanning electrochemical microscopy, invented by our group, in imaging and analyzing surface structures, measuring reaction rates, and performing high resolution fabrication.
