Computational molecular modeling has become an important tool of inquiry over the course of the last two decades. In particular, modern methods like Density Functional Theory (DFT) have allowed new perspectives on classical problems of inorganic chemistry, like redox chemistry. In this presentation I will review efforts from my research group towards utilizing DFT to better understand redox processes that are difficult to understand using classical tools of research:
Redox reactions are most conveniently studied using cyclic voltammetry (CV). To precisely determine the normal reduction potential of a redox pair, the average of the cathodic and anodic peak potentials are commonly taken. This simple and robust protocol becomes useless when the electrochemical reduction is coupled to an irreversible chemical reaction, as the corresponding anodic peak vanishes and the CV only shows a cathodic peak. Through a combination of computations and a careful shape analysis of such irreversible Faradaic response, we were able to not only extract the normal potential, but also to obtain kinetic information that is difficult to assess by other means.
This example of integrating theory and experiment in a single seamless effort highlights how we can leverage very simple techniques into a synergistic framework of investigation.
