Abstract
Adsorption of reactants and reaction intermediates on solid catalytic surfaces can lead to significant changes of the surface structure, including, as shown in high-pressure Scanning Tunneling Microscopy (STM) experiments, ejection of metal atoms and formation of metal clusters while the reaction is taking place. Depending on the specific system, these clusters provide new, more favorable reaction paths than the typically considered active sites. In this talk, we will attempt to provide a more realistic picture of the catalyst’s surface and its active sites as a function of reaction conditions and the identity of reactants and that of key intermediates. Insights derived from our analysis can inform the design of new catalysts with improved activity, selectivity, and stability characteristics.
Bio
Manos Mavrikakis is the Ernest Micek Distinguished Chair, the James A. Dumesic Professor, and the Vilas Distinguished Achievement Professor of Chemical Engineering at the University of Wisconsin-Madison. He received a Diploma in Chemical Engineering from NTUA in Greece, and a PhD in Chemical Engineering & Scientific Computing from the University of Michigan, Ann Arbor. Following postdocs at the University of Delaware and the Technical University of Denmark, he joined the faculty of Chemical Engineering at UW-Madison. His main research interests include the elucidation of detailed reaction mechanisms for thermal heterogeneously catalyzed and electrocatalyzed reactions and the identification of improved catalytic materials from first-principles-based microkinetic modeling. He has coauthored ~300 publications. Mavrikakis is an elected Fellow of APS (2013), AAAS (2014), and AVS (2016). He served as his Department Chair (2015-2018) and was a Visiting Miller Research Professor at UC Berkeley – Chemistryin 2019. He received the 2009 Paul H. Emmett award and the 2021 Burwell Lectureship from the North American Catalysis Society, the 2014 R. H. Wilhelm award from AIChE, and the 2019 Gabor A. Somorjai award from ACS. He served as editor-in-chief of Surface Science between 2012 and 2020.
