Description

Accurate models of the electrochemical interface are a key for predicting reaction mechanisms and designing improved electrocatalysts, reactants, and electrolytes. The properties of electrochemical interfaces depend both on the surface structure and the interactions with the electrolyte as a function of applied potential. Despite more than a century of model development, much is still unknown about even single-crystal interfaces. We combine spectroscopic and structural techniques for probing the interface, such as SEIRAS and STM, with computational methods to develop new electrochemical models. The computational work focuses on combining DFT methods for the surface with continuum approaches for the electrolyte. Work is needed both to improve the computational methods, as well as apply them to electrochemical problems. An individual NRC project can either include both theory and experiment, or focus on a single technique.
