Prof. Brandi M. Cossairt

Thursday, June 15, 2023, 5:00 – 6:00 pm ONLINE ONLY

Department of Chemistry at the University of Washington
Associate Editor of Inorganic Chemistry (ACS)

Her research focuses on the construction of inorganic nanostructures for targeted applications in classical and quantum light emission, hybrid materials, energy generation and catalysis. Using the tools and methods of inorganic and main group synthesis, she fabricates new III-V nanostructures and clusters and designs colloidal and homogeneous catalysts and electrocatalytic interfaces.

Topic: “Interfacial Chemistry as an Enabling Tool in the Development of Solution Processed Nanomaterials for Catalysis”


Controlling the interfaces of materials alters their ability to transfer charge through inner-sphere active site control, by altering outer-sphere active site-substrate interactions, and through modulation of the electrochemical double layer. To leverage interfacial chemistry in the design of heterogeneous catalysts, we are developing new methods for the post-synthetic modification of solution-processed nanocrystals and nanostructured thin films. In this talk, ligand exchange, surface etching, covalent modification, and intercalation will be presented as complementary methods for altering the electrochemical activity of colloidal transition metal phosphide and dichalcogenide materials. A combination of electrochemical characterization, physical and electronic structure analysis, and computation will be presented. Together with stoichiometric probes of inner-sphere reactivity, these data reveal mechanistic details of charge transfer and catalysis in these systems. This work has led us to propose that the presence of diverse adsorption sites on transition metal phosphide surfaces may be leveraged for selective and efficient hydrogenation and electrochemical reduction reactions beyond hydrogen production, including nitrate reduction, which will also be discussed. Finally, if time permits, the development of new tools to measure photoinduced charge transfer from semiconductor nanocrystals will be highlighted.

The CRC cordially invites all who are interested to the lecture!
