Catalytic Nanomaterials for Electrochemical Energy Storage and Conversion

Electrochemistry and electrocatalysis play pivotal roles in the science and technology of chemical energy storage and conversion. Devices such as electrolyzers, photoelectrochemical cells, or fuel cells constitute electrochemical reactors where all relevant molecular processes occur. There, storage and conversion is put into effect via molecular bond making and breaking, catalyzed at electrified interfaces of an ion conductor and an electrocatalyst material.  For these reactions to occur with the smallest possible energy losses and the utmost atom efficiency, nanostructured multi-component electrode materials have proven indispensable, because they offer substantial advantages in atomic dispersion, resulting in energy efficiency and performance benefits.

All this taken together is why energy-related electrocatalysis and the science of nanomaterials have formed an irrevocable symbiosis. The successful development of novel nanostructured electrocatalyst materials, however, requires insight into the relation between their atomic-scale structure and their catalytic performance. Unraveling such relations is thus a scientific priority.

In this talk, I will highlight some advances of our recent work on the design and understanding of structure-activity relations of nanostructured electrocatalytic materials and their liquid-solid interfaces ^1-10. Topics covered will include the oxygen electrode under acid and alkaline conditions, as well as the direct electroreduction of CO₂.
