Studying Nanoscale Processes in Bimetallic Nanoparticles using In Situ Electron Microscopy

Speaker: Dr. See Wee Chee

Date: 24 April 2019 (Wednesday), 10:00 am

Venue: AToM@FACTS, Academic Building North, ABN-B4B-10


Bimetallic nanoparticles (NPs) are promising candidate materials for applications in catalysis, plasmonics and biomedical research. Hence, there is significant interest in either synthesizing NPs with more complex morphologies or modifying these NPs with heat treatments to achieve tailored nanostructures with better performance. In this talk, I will discuss how we used in situ transmission electron microscopy (TEM) to gain insights into (1) galvanic replacements reactions between Ag nanoparticles and aqueous Au solutions and (2) the manifestation of the Kirkendall effect in core-shell nanoparticles made of Au and Pd. In (1), we used liquid cell TEM to reveal the mechanism of hollow structure formation during the reactions. In (2), we show that the interdiffusion of metals in Au-Pd diffusion couples lead to an unconventional form of the Kirkendall effect where vacancies diffuse towards Au, the slower diffusing species, and void formation at the bimetallic interface. Lastly, I will briefly discuss opportunities for operando studies of nanoscale reactions where we combine in situ TEM with measurements of reaction kinetics.
