Today, 75% of the anthropogenic greenhouse gas emissions come from carbon dioxide from the energy and chemical sectors. In the future, CO2-free transportation fuels along processes that produce solid phase carbon or storable carbonates will be important as CO2 emissions become increasingly undesirable and costly to emit. The overall goal of our research is to understand and develop catalysts and processes to produce chemicals, power, and materials in environmentally sustainable ways.

Experiments in CHBE’s Catalysis Labs are used to infer mechanisms and develop new catalysts. The techniques used include operando IR spectroscopy, pulsed and transient analysis of reaction mechanisms, isotopic labeling studies, in-situ X-ray absorption spectroscopy, and many other characterization tools. Modeling and collaborations with theorists enhance our understanding. We are particularly interested in understanding how liquid heterogeneous catalysts behave under reaction conditions.
