Abstract

The current energy crisis experienced by society today is in desperate need of a solution. Through carbon dioxide (CO2) reduction, we can reduce the amount of greenhouse gas that is warming our planet as well as create a source of renewable energy. Significant challenges currently inhibit the reduction of CO2 to more desirable products. Current limitations can be addressed through the design and synthesis of more efficient catalysts that are selective, durable, and operate close to the target thermodynamic potential of CO2 reduction. In this work, three redox-active macrocyclic ligands have been synthesized and studied for the development of potential catalysts for electrochemical CO2 reduction. The implementation of all three ligands varied, and ultimately electrocatalytic results with a novel ruthenium-based complex were obtained via cyclic voltammetry and controlled potential electrolysis.
