CBC Colloquium: Professor John F. Berry
The Department of Chemistry and Biochemistry's Colloquia Series is proud to present "New Chemistry of Metal-Metal Bonded Compounds: Toward a Nitrogen Energy Economy" by John F. Berry, professor in the Department of Chemistry, University of Wisconsin – Madison.
Ammonia has arisen as an attractive potential large-scale energy carrier due to its improved storage and transport over hydrogen, provoking calls to explore a potential nitrogen economy. Two fundamental technologies are needed in order to realize a zero-carbon nitrogen energy economy: (1) Ammonia synthesis from solar electricity, and (2) high-performance direct ammonia fuel cells. Both are mechanistically challenging multi-proton, multi-electron transformations, prompting investigations into the fundamental coordination chemistry and reactivity of ammonia with transition metals. We report unusual reactivity of ammonia with metal-metal bonded compounds that results in the spontaneous metal-centered reduction and oxidation of ammonia to dinitrogen. Mechanistic aspects of this chemistry will be presented as well as results on electrocatalytic oxidation of ammonia to dinitrogen.
Light refreshments will be served prior to the seminar. All are welcome to attend.
Hosted by CBC assistant professor Thomas Gianetti and the Department of Chemistry and Biochemistry.
