报告人简介：

Intermetallic nanoparticles (NPs) are a class of transition metal-based alloy NPs within which metal atoms are bonded via strong d-orbital interaction in a specific crystallographic direction. Compared to the common metallic alloy NPs with solid solution structure, intermetallic NPs are generally more stable against chemical oxidation and etching, making them an ideal choice as catalysts in corrosive reaction systems.

This talk focuses on monodisperse intermetallic L10-structured MPt NPs, especially Pt-, Pd-, and Au-based L10-NPs, as robust catalysts for electrochemical reduction and oxidation reactions.

报告摘要：

Shouheng Sun received his BSc from Sichuan University (China), MSc from Nanjing University (China), and PhD from Brown University (USA). He joined the IBM T. J. Watson Research Center (Yorktown Heights, New York, USA) first as a postdoctoral fellow (1996-1998) and then as a research staff member (1998-2004). In 2005, he returned to Brown University as a tenured Associate Professor and was promoted to full Professor in 2007. He has been the Vernon K. Krieble Professor of Chemistry and Professor of Engineering since 2016. His main research interests are in chemical synthesis and self-assembly of nanoparticles for catalytic, magnetic and biomedical applications. He served as a co-Director of Brown’s Institute of Molecular and Nanoscale Innovation (2008-2020) and an Associate Editor for the Royal Society of Chemistry Journals, Nanoscale and Nanoscale Advances (2012-2021). He has been a Fellow of the Royal Society of Chemistry since 2015.
