The increase in worldwide demand for energy, coupled with the proposed role of CO2 on global warming and the eventual depletion of fossil fuels, necessitates the development of new technologies for the efficient conversion of energy. The objective of my research program is to improve catalytic processes that are pertinent to future energy schemes. We have contributed to electrochemical, photochemical and thermal systems. This entails ligand/catalyst design, establishing how catalyst structure impacts reactivity/energetics, and determining how reaction conditions alter the energetic profile. These concepts can all be distilled down to our desire to understand how to tune the thermodynamics and kinetics of reactive intermediates, particularly metal hydrides. Given the importance of metal hydrides to many reactions, the different modes of reactivity (proton, H-atom, or hydride transfer), and the commonality of similar metal hydride intermediates in different reactions (for example, H2 evolution versus CO2 reduction to formate), understanding how to control reactivity is of great importance.
Members of my group will become proficient in a variety of techniques, for example: (i) organic/inorganic synthesis (including glove-box, Schlenk, and high-vacuum techniques), (ii) multi-nuclear and VT-NMR, IR, and UV-vis spectroscopy, (iii) electrochemistry, (iv) single crystal X-ray diffraction, and (v) analysis of kinetic data. Other techniques such as EPR spectroscopy, SQUID magnetometry, and DFT calculations may also be utilized.
