"Increasing Energy Efficiency in Chemical Production: Translation of Fundamental Surface Chemistry to Catalysis"
Sustainable catalytic processes are critical to solving the challenges in energy production and reduction in CO2 production. Catalytic processes generally and reaction selectivity specifically are by their nature kinetically controlled. To fully understand the kinetics of catalytic processes, understanding the elementary reactive steps and the state of the catalytic material under reaction conditions is essential. The reactive elementary steps provide a means of modeling and predicting kinetics and reaction selectivity. At the same time, the state of material, including the composition, geometric and electronic structure of reactive sties must be defined under operating conditions because these are all factors in determining catalytic function of a material. Selected examples of Au-based nanoporous catalysts will be used to illustrate the combined use of fundamental studies to determine reaction mechanism and kinetics with in situ studies using ambient pressure XPS and environmental TEM to follow the evolution of catalytic material under reaction conditions. This work will be generalized to illustrate how efficient and sustainable catalytic processes can be designed.
Professor Friend is the Theodore Williams Richards Professor of Chemistry in the Department of Chemistry and Chemical Biology, and a professor Materials Science in the School of Engineering and Applied Science at Harvard University. She is director of the Rowland Institute at Harvard, and director of the Department of Energy-sponsored Energy Frontier Research Center on Integrated Mesoscale Architectures for Sustainable Catalysis.
Her research focuses on important catalytic reactions and on making new materials with key chemical functionality. The major research themes in her group are heterogeneous catalysis, surface chemistry, geterogeneous photochemistry, and theory collaboration.
Izaak Maurits Kolthoff Lectureship in Chemistry
Izaak Maurits Kolthoff was born on February 11, 1894, in Almelo, Holland. He died on March 4, 1993, in St. Paul, Minnesota. In 1911, he entered the University of Utrecht, Holland. He published his first paper on acid titrations in 1915. On the basis of his world-renowned reputation, he was invited to join the faculty of the University of Minnesota’s Department of Chemistry in 1927. By the time of his retirement from the University in 1962, he had published approximately 800 papers. He continued to publish approximately 150 more papers until his health failed. His research, covering approximately a dozen areas of chemistry, was recognized by many medals and memberships in learned societies throughout the world, including the National Academy of Sciences and the Nichols Medal of the American Chemical Society. Best known to the general public is his work on synthetic rubber. During World War II, the government established a comprehensive research program at major industrial companies and several universities, including Minnesota. Kolthoff quickly assembled a large research group and made major contributions to the program. Many of Kolthoff’s graduate students went on to successful careers in industry and academic life and, in turn, trained many more. In 1982, it was estimated that approximately 1,100 doctorate holders could trace their scientific roots to Kolthoff. When the American Chemical Society inaugurated an award for excellence in 1983, he was the first recipient.
