Title: “Shining Light on Cluster and Nanoparticle Catalysts”
Friday, Nov. 17, 2017 @ 3:00 p.m.
Room #186 Essex Hall
In this seminar, I will discuss work in our group focusing on the development of cluster and nanoparticle catalysts which have high catalytic activity, excellent selectivity towards specific substrates, and excellent durability and recyclability. Our current work involves the synthesis and stabilization of clusters and nanoparticles in solution followed by activating them for catalysis. Several routes towards such goals will be discussed, including the activation of monolayer-protected Au clusters and structural control of bimetallic nanoparticles. Characterization tools which can assist in elucidating surface chemistry and/or cluster and nanoparticle sizes and structures will be detailed, including mass spectrometry, HRTEM, and in situ x-ray absorption spectroscopy at the Canadian Light Source.
