Tailoring and understanding the structure of the electrochemical interface at the atomic level is key to elucidating the design principles for the discovery of new electrocatalysts for renewable energy conversion. This talk will focus on our recent work on new catalyst (nano)materials and engineered interfaces for electrochemical energy conversion and storage. In particular, I will discuss structure sensitivity and electrolyte effects for oxygen and carbon dioxide/carbon monoxide electrocatalysis.
First, I will present our work toward understanding and tuning the structure-activity-stability relations for oxygen reduction [1] and oxygen evolution [2], for applications in fuel cells and water electrolysers, respectively. Then, I will discuss our model studies on Cu-based surfaces to understand structure-properties relations for CO2 reduction [3-4]. We have investigated the effect of pH, specific anion adsorption, and potential dependence for CO reduction on Cu single crystals. We show how well-defined studies are essential to design efficient electrocatalysts to produce renewable fuels.
