Carbon dioxide is quite stable, and thus development of catalytic systems for its conversion into more useful chemicals is challenging. Moreover, carbon dioxide is a gas with limited solubility in most solvents at near-ambient pressures, limiting the usefulness of even the most active catalysts. These difficulties are compounded in electrochemical cells, where the catalytic chemistry is fundamentally limited by diffusion of the substrate and/or catalyst to the electrode surface. Here, we will discuss our recent work to develop carbon dioxide-rich organic solvents as media for electrochemistry and CO<sub>2</sub> conversion. Our latest results from chemical work and electrochemical investigations suggest that the presence of high concentrations of CO<sub>2</sub> offers useful advantages over more traditional studies at near-ambient pressures. These advantages and new opportunities will also be discussed.
