Summary
This presentation will deal with the use of operando methods for mechanistic studies energy systems with emphasis on fuel cells and battery materials and technologies. The presentation will begin with a brief overview of the methods employed with emphasis on the use of X-ray based methods, transmission electron microscopy (TEM) under active potential control and confocal Raman spectroscopy. The utility of these methods will be illustrated by case studies focusing on non-precious metal electrocatalysts for the oxygen reduction reaction (ORR) in alkaline media, Li/S batteries and the reduction of carbon dioxide. The presentation will conclude with an assessment of future directions.
