主讲人/Speaker:

Jian-Feng Li is a full Professor of Chemistry at Xiamen University. He received his BSc degree in Chemistry from Zhejiang University in 2003, and his PhD degree in Chemistry from Xiamen University in 2010. He worked as a postdoctoral researcher at the University of Bern and ETH Zurich in Switzerland from 2011 to 2014.

Professor Li’s research interests include core-shell nanomaterials, surface-enhanced Raman spectroscopy, in-situ characterization, electrochemistry, surface catalysis, and rapid detection using a portable Raman instrument. He has published more than 360 peer-reviewed papers, with a total citation count of over 25000, including those in Nature, Nat. Nanotechnol., Nat. Mater., Nat. Energy, Nat. Catal., etc.

Jian-Feng Li serves as a Senior Editor of J. Phys. Chem. C, and the International Steering Committee (ISC) of the International Conference on Raman Spectroscopy (ICORS). He has organized several international conferences as the chairman and has been invited to give plenary and keynote talks at international conferences related to spectroscopies and electrochemistry.

He has received numerous prestigious awards, including the National Natural Science Award (Second Prize, China), the Chinese Excellent Young Science and Technology Talents Award, the National Science Fund for Distinguished Young Scholars, the Xplorer Prize, and the Advances in Measurement Science Lectureship Award (ACS).

摘要/Abstract:

Surface-enhanced Raman spectroscopy (SERS) can provide fingerprint structural information of molecules with ultrahigh surface sensitivity. However, only a few metals, such as Au, Ag, and Cu, with specific nanostructures can generate strong SERS effects. Such material and morphology limitations have greatly hindered the applications of SERS.

To overcome the long-standing material limitation of SERS, we developed various methodologies, including the “borrowing” strategy, shell-isolated nanoparticle-enhanced Raman spectroscopy (SHINERS), and the SHINERS-satellite strategy, through the fabrication of different core-shell nanostructures. Using these strategies, the molecular configuration of water at various electrochemical interfaces and its evolution in response to the electrochemical environment have been probed. Furthermore, the dynamic processes of critical catalytic reactions occurring on model single-crystal surfaces, practical nanocatalysts, or even single-atom catalysts, such as the oxygen reduction reaction, the hydrogen evolution reaction, and electrooxidations, have been systematically investigated. Direct spectroscopic evidence has been obtained for the key intermediates (*OH, *OOH, *O2-, etc.) during reactions, which is combined with theoretical simulation to uncover the reaction mechanisms or structure-activity relationships at a molecular level.

The concept of shell-isolated nanoparticle-enhancement is being applied to other spectroscopies, such as fluorescence, IR, SHG, SFG, and tip-enhanced spectroscopies, to improve sensitivity or spatial resolution.
