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.
