The Holewinski group is focused on efficient, renewable, and environmentally benign catalytic processes for the production of energy, as well as commodity and fine chemicals. We have particular interest in electrochemical routes—i.e. the direct interconversion between electrical energy and the energy of chemical bonds. Emphasis is placed on fundamental characterization of interactions between molecules and (electro)catalytic surfaces to understand reaction mechanisms for the design and optimization of next-generation catalysts. Broadly, we employ molecular-level insights from detailed kinetic analysis, quantum chemical calculations, and spectroscopic observations of reactive species and catalyst structures to discern the chemistry and physics relevant to catalyst performance. These insights enable informed, targeted catalyst synthesis strategies to attain ideal structures and compositions that facilitate desirable transformations.
