| Abstract Scope |
Recent advances in advancing new catalysis science have paved the way for discovering emergent materials with unique properties. This talk will explore the application of advanced X-ray spectroscopy techniques in investigating the electronic and coordination structural properties of catalysts under electrocatalysis conditions. Building on our published work on electrochemical CO2 reduction, I will discuss the modulation of catalytic pathways by varying active site dimensions, as demonstrated in Sn and Cu-based catalysts. These studies highlight the potential of transition metal such as Cu and p-block elements such as tin as cost-effective catalysts for CO2 conversion to multi-carbon organics. By employing operando X-ray techniques, we aim to elucidate the dynamic transformations of catalytic sites and their impact on reaction mechanisms. This research not only advances our understanding of catalysis under extremes but also offers insights into designing next-generation catalysts for sustainable chemical production. |
