Prof. Christophe Coperet : Understanding Catalysis, one Atom at a Time
Abstract: Keywords: Single sites, Single Atom Catalysts, Nanoparticles
Most efficient chemical processes used in industry rely on heterogeneous catalysis. While the search for more sustainable processes and the changes in environmental policies impose the continuous development of more efficient catalysts, we have currently little understanding of the structure of the actives in these processes. Hence, due to their inherent complexity, heterogeneous catalysts have been mostly developed empirically.
Here, we will show how constructing active sites, one atom at a time on surfaces, enables molecular-level understanding and implementation of rational approaches for the improvement of catalytic processes. We will first illustrate how this approach enables to generate selective single-site catalysts. We will next show how from these isolated (single) sites, one can generate and understand far more complex systems such as supported nanoparticles, where interfaces, alloying, etc… play a critical role. This lecture will be developed around these themes and will show how the development of advanced characterization tools augmented by computational approaches can provide useful information to bridge the gap between fundamental and applied (industrial) catalysis.
Bio: Christophe Copéret has been Professor of Surface and Interface Chemistry at the Laboratory of Inorganic Chemistry in the Department of Chemistry and Applied Biosciences, since 2010. He was born in Belleville, France in 1970. Christophe Copéret completed his degree in chemistry and chemical technology at the University of Lyon in France in 1992. He obtained a doctorate from the Purdue University in West Lafayette, IN, USA in August 1996 before working as a postdoc for a year under professor K. B. Sharpless at Scripps Research Institute in La Jolla, California, USA. From 1998 to 2002, he was an assistant professor at the University of Lyon. In 2002, he became a professor at the University of Lyon, where he worked for another eight years. From 2008 to 2010, he was Research Director of the CNRS (Centre national de la recherche scientifique). Christophe Copéret was an Associate Editor of the Journal of Catalysis (2011-2015), and the Co-Editor in Chief of Helvetica Chimica Acta, the journal of the Swiss Chemical Society (2016-2021). Since 2022, he is an Associate Editor of the Journal of the American Chemical Society, JACS.
