报告人简介：
Yang Hu is an Associate Professor at the Technical University of Denmark (DTU). He received his B.S. degree from Jilin University in 2009 and his PhD from the Changchun Institute of Applied Chemistry, Chinese Academy of Sciences, in 2015. He currently leads the In-operando Electrocatalysis Group at DTU. His research focuses on the development and application of in-operando techniques for studying electrocatalysts, with particular emphasis on catalyst synthesis for precise structural control and on the evolution of catalyst structures and interfaces under industrially relevant operating conditions. The group’s research is closely linked to applications in electrolyzers, fuel cells, and the electrosynthesis of e-fuels and e-chemicals. His group has developed and applied a broad suite of in-situ and in-operando characterization techniques to investigate catalyst synthesis mechanisms and structural evolution under working conditions, including high-temperature XRD, TGA-MS, TPR-MS, in-situ TEM, and identical-location TEM for studying catalyst synthesis processes, as well as in-operando electrochemical XRD, surface-enhanced IR and Raman spectroscopy, in-line ICP-MS, and environmental XPS for probing the structural evolution of electrocatalysts across diverse applications.
讲座摘要：
Electrocatalysis underpins a range of critical technologies needed for the Green Transition from fossil fuel–based energy systems to a sustainable future. The precision synthesis of electrocatalysts with well-defined structures, together with an understanding of their dynamic structural transformations under operating conditions, is essential for developing electrocatalysts that are active, selective, and, especially, durable for industrial applications. Here, I will present the latest results from our group on in operando studies of the synthesis of supported Pt- and Ir-based electrocatalysts, as well as their structural evolution under industrially relevant operating conditions of polymer electrolyte membrane fuel cells and electrolyzers. A range of in-operando techniques have been employed to provide complementary insights into the physical and chemical processes involved during catalyst synthesis and electrochemical testing. We believe the presented results represent a small but solid step toward the atomically precise synthesis of electrocatalysts with predictable catalytic properties tailored to their intended working conditions.
