Research Areas: Electrocatalysis, inorganic chemistry, organometallics, small molecule transformation. Research: Furthering alternative energy research is of upmost importance as the negative effects of man-made carbon emissions are becoming much clearer. Modern energy challenges involve the catalytic transformation of inert small molecules through redox events. Electrochemical methods will play a large role in discovering and further developing catalysts capable of these transformations. Development of Photocatalytic Systems for Fuel Production: Efficient conversion of light-to-chemical energy provides an attractive approach to the development of alternative energy sources. The production of fuels such as H2 and light hydrocarbons from a renewable, carbon neutral source and sunlight is an important technological goal for energy research and sustainability. Work in the group on this project focus on developing inorganic chromophore-catalyst assemblies for the production of fuel without the use of chemical sacrificial electron donors. Electrochemically Driven Reductive C–C Coupling: Carbon-carbon cross coupling is arguably the most important class of organic reactions, but is still limited with respect to coupling molecules containing β-hydrogen atoms, which are important in the formation of higher hydrocarbons and in drug discovery. Developing electrochemical reductive cross coupling chemistry with kinetically facile routes for C–C coupling products offers a mechanistic scheme to prevent unwanted β-hydride elimination products. This project furthers the development and applicability of electrochemically driven reductive cross coupling reactions, with a focus on expanding cross coupling reactions beyond the limitations of currently utilized routes. In addition, the reductive C-C coupling scheme is ideal for incorporating catalytic carboxylation reactions using carbon dioxide as an inexpensive and completely renewable chemical feedstock. The utilization of CO2 for the production of fuels, polymers, and synthetic precursors could also help mitigate current CO2 emission problems
