The work in this dissertation overviews the fundamental electrochemical, physical, and spectroscopic analysis of redox-active systems for CO2 electrocatalysis and energy storage. With global impacts from climate change, decreases in carbon emissions have come through producing and storing energy with carbon-free renewable sources, as well as the conversion of carbon sources such as CO2 into value-added products. My research spans both of these approaches, from the study of organic redox-active molecules for intermittent energy storage to the systematic electrochemical characterization of electrocatalysts designed for CO2 reduction. While my research projects are distinct, they are linked through the common theme of using electrochemistry and the information it provides to improve energy technologies. My energy storage research focuses on the systematic characterization of a series of non-aqueous organic redox-active molecules for use in redox flow batteries. Various concentrations of redox-active species and electrolyte are electrochemically characterized to elucidate the implication of concentration on battery performance parameters. Spectroscopic analysis also reveals information on the solvation environments of these species at varying concentrations and charge states and the impact of intermolecular interactions on electron transfers.My work in CO2 electrocatalysis explores coordination complexes with metal-ligand cooperativity (MLC) and redox-active ligands, both of which can be tuned to impact substrate binding strength and catalytic activity. Fundamental electrochemical characterization of a series of these coordination complexes is coupled with equilibrium modeling to quantify binding strength and ultimately connect it to electrochemical properties and ligand design. Insights from this work inform the design of coordination complexes that are then tested for preliminary electrochemical CO2 reduction performance.
