Abstract:
The results of research efforts aimed towards fundamental understanding of processes that are relevant for energy conversion and storage will be presented. Atomic scale insight at electrified solid-liquid interfaces is considered critical for further advancement of materials for electrochemical systems such as electrolyzers, batteries and fuel cells.
It has been demonstrated that fine tuning of material properties can lead towards unprecedented improvements in functional behaviors that are relevant for energy conversion and storage systems. This presentation will describe a unique research approach that is capable of revealing structure-function relationships in the design of nanomaterials for electrochemical applications. The following topics will be discussed: 1) well-defined materials obtained by varying their surface structure, composition profile and electronic properties; 2) atomic/molecular insight into electrified solid-liquid interfaces; 3) modeling of electrochemical systems; 4) identification of the most Sactive and the most vulnerable surface sites under reaction conditions; 5) insight into the chemical nature of surface atoms, reactants, and molecular species in the electrolyte; 6) engineering of advanced nanomaterials with desired size, shape and composition profile; 7) ex-situ and in-situ characterization of tailored nanostructured electrochemical interfaces.
This synergistic approach encompasses highly diverse experimental and theoretical methods and has been proven to serve as a foundation for the development of novel nanomaterials with advanced properties.
