Catalyst Discovery

CO2 Reduction

The increasing levels of CO2 has become one of the most important problems of our current society.  Importantly, chemistry will play a key role in finding the solution to this challenge. Our laboratory is interested in elucidating the chemical mechanisms by which inorganic-based catalyst transform CO2 into other molecules. For this purpose, we are using 13C kinetic isotope effects (13C KIEs). With this information in hand, we plan to synthesize new molecules that can catalyze the conversion of CO2 with faster rates and selectivity.
