        报告地点：第二化学楼101学术报告厅

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.（金属间纳米颗粒(NPs)是一类过渡金属基合金NPs，其中金属原子通过强d轨道相互作用在特定的晶体学方向上结合。与具有固溶体结构的普通金属合金NPs相比，金属间NPs通常具有更好的抗化学氧化和腐蚀性能，是腐蚀反应体系中催化剂的理想选择。本讲座主要介绍单分散的金属间L10结构MPt NPs，特别是Pt, Pd和Au基L10-NPs，作为优异的电化学还原和氧化反应的催化剂。)

  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.（孙守恒，美国布朗大学教授。曾先后获四川大学理学学士、南京大学理学硕士，美国布朗大学博士学位。1996年作为博士后加入IBM T. J.
