研究领域

Semiconductor Electrochemistry and Photocatalysis Attempts at developing efficient and stable photoelectrochemical (PEC) conversion systems have more recently led to exploring the potential and power of PEC methods for non-energy related research. Topics under study include novel in situ diagnostic tools for semiconductor film formation, and spectroscopic probes of charge and mass transport at semiconductor/electrolyte interfaces. We are also investigating the mechanisms of heterogeneous photocatalysis for toxic waste treatment and disinfection. A recent area of interest is solar hydrogen production. Conducting Oxides and Polymers In this area, our interests lie with charge and mass transport mechanisms, the development of novel in situ analytical probes of ion transport, and the chemistry/materials aspects of device applications including sensors, fuel cells, and capacitors. Environmental Electrochemistry We are interested in novel electrode materials for toxic waste treatment and chemical sensing of pollutants.
