The group is interested in developing new catalysts for energy conversion, for electro- and thermo- catalysis. Reactions of interest include CO2 reduction (as well as capture) and methane oxidation. New catalysts such as high entropy metals are of interest. Plasma enhanced reactions that can energy efficiently convert hydrocarbons, CO2, Ammonia etc. to utilizable liquid and solid products and hydrogen are areas the group is working on. Other energy conversion platforms such as photo-thermal, photo-voltaic, thermoelectric and ferro/pyro-electric are also of interest from the point of view of materials development and characterization are also of interest.
