报告摘要：
The electrochemical conversion of abundant molecules into valuable chemicals and fuels using renewable electricity is central to the development of sustainable energy and production technologies. Achieving efficient, selective, and scalable processes requires advanced catalysts and a deeper understanding of how they operate under realistic working conditions. In particular, catalyst structures are often highly dynamic during operation, and these transformations can strongly influence catalytic performance.
This talk will highlight how catalytic materials undergo significant structural and chemical changes under reaction conditions, and how these evolving states govern reaction activity, selectivity, and stability. Examples from several important electrochemical reactions, including the electrocatalytic CO2 reduction (CO2RR), nitrate reduction to ammonia, and the oxygen evolution reaction (OER) will illustrate the relationship between the catalyst dynamics and functionality across a range of material systems comprising Cu single crystals, Co and Ni oxide thin films, nanoparticles (Cu2O, NiOx, CoOx, Co(OH)2, CoFeOx) and single-atom catalysts (metal-N-C).
Emphasis will be placed on the importance of operando and in situ characterization combining microscopy, spectroscopy, and diffraction techniques to monitor the transformations of the catalysts. This approach will provide key insight into catalyst activation, deactivation, and regeneration processes, as well as into the influence of the reaction environment, including electrolyte composition (cations) and impurities (Fe), on the catalyst behavior and performance.
