报告人简介：
Dr. Zhiqun Lin is currently Professor of Chemical and Biomolecular Engineering at the National University of Singapore (NUS). He received his BS degree in Materials Chemistry from Xiamen University in 1995, Master degree in Macromolecular Science from Fudan University in 1998, and PhD degree in Polymer Science and Engineering from University of Massachusetts, Amherst in 2002. He did his postdoctoral research at University of Illinois at Urbana-Champaign. He joined the Department of Materials Science and Engineering at the Iowa State University as an Assistant Professor in 2004 and was promoted to Associate Professor in 2010. He moved to Georgia Institute of Technology in 2011, and become a Professor in 2014. He relocated to National University of Singapore in 2022. His research interests include solar cells, photocatalysis, electrocatalysis, batteries, block copolymers, conjugated polymers, functional nanocrystals, hierarchically structured and assembled materials, and surface and interfacial properties. He has published more than 450 peer reviewed journal articles (with an h-index of 129), 19 book chapters, and 9 books. He is a Fellow of MRS, ACS, AAAS, and RSC. Currently, he serves as a co-Editor-in-Chief of Nano Energy.
报告内容简介：
Conventional strategies such as optimizing morphology, composition, and electronic structure have achieved notable enhancement in catalytic performance, yet approaching their intrinsic limit in activity improvement. Overcoming such limitations requires new strategies that can dynamically modulate catalytic energetics during operation rather than relying solely on static material design. In this context, the application of external fields has emerged as a powerful paradigm for catalyst regulation. External magnetic, photo, and thermal fields can introduce new degrees of freedom that reshape charge, spin, and lattice dynamics, thereby enabling kinetic pathways that are inaccessible under conventional conditions. These external fields can act cooperatively, producing synergistic effects that transcend the sum of their independent contributions. In this talk, I will discuss the unravelling of synergy of magnetic field and chiral-induced spin selectivity (CISS) effect to promote oxygen evolution reaction activity. Subsequently, I will introduce a robust strategy that leverages CISS, ferroelectricity, and photocatalytic heterostructures to significantly improve charge carrier dynamics, offering a promising pathway for plastic photoreforming into value-added products.
