Formation, Segregation, and Degradation of Nanostructured Catalysts for Electrochemical Conversion and Storage

We present recent progress in the development of nanostructured catalysts for electrochemical conversion and storage of electrical energy. We will address atomic scale insights in the synthesis, segregation, and degradation of shaped Pt bimetallic catalysts using ex-site and in-situ aberration-correction microscopy. We also highlight the use of CO as a size confining agent in the synthesis of bimetallic nanoparticles. Finally, we will discuss the structure, morphology and surface chemistry during the formation and catalysis of bimetallic Ir-Ni core shell particles for the electrolytic splitting of water in acidic media.
