A promising approach in developing catalytic materials is represe nted by the design of catalytic sites based on the knowledge of reaction m echanisms and structure-property relationships and aided by computation\, and in the precise synthesis of these sites at the atomic and molecular le vel. The materials-pressure gap\, however\, still hinder the full realizat ion of this strategy. Nanocrystal precursors\, with tunable active sites a nd compositions\, can help bridge this gap. The goal of this talk is to sh ow how this approach can provide not only fundamental understanding of cat alytic reactions\, but also represent a way to precisely engineer catalyti c sites to produce efficient catalysts that are active\, stable and select ive for several important catalytic transformations. Advances in the synth esis of these materials will be presented\, in order to better understand the mechanism of colloidal nanocrystal formation\, to control their struct ure and composition at the nanometer level. Examples of the use of these b uilding blocks as supported systems or in combination with hybrid organic materials will be shown\, both to understand trends in methane and CO2 act ivation\, and in the preparation of optimized catalytic systems combining multiple active phases. In all these examples\, important efforts to obtai n precious structure-property relationships will be highlighted\, with thi s knowledge used to prepare more efficient catalysts for sustainable produ ction of fuels and chemicals.\n\nMatteo Cargnello received his Ph.D. in Na notechnology in 2012 at the University of Trieste (Italy) under the superv ision of Prof. Paolo Fornasiero\, and he was then a post-doctoral scholar in the Chemistry Department at the University of Pennsylvania (Philadelphi a) with Prof. Christopher B. Murray before joining the Faculty at Stanford in January 2015. He is currently Assistant Professor of Chemical Engineer ing and Terman Faculty Fellow at Stanford University\, Stanford\, CA. Dr. Cargnello is the recipient of several awards including the ENI Award Debut in Research 2013\, the European Federation of Catalysis Societies Award a s best European Ph.D. thesis in catalysis in 2013\, the Young Scientist Pr ize at the 16th International Congress on Catalysis in 2016\, the Junior a ward from the European Rare Earth and Actinide Society in 2018\, and the S loan Fellowship in 2018. General goals of the research in the Cargnello gr oup pertain to solving energy and environmental challenges. In the Cargnel lo group\, uniform and tailored nanocrystals and nanostructures are synthe sized\, studied and used for energy and environmental applications through catalytic processes\, with emphasis on how to precisely control nanoarchi tectures to understand and exploit interactions between well-defined build ing blocks.\n\n  LOCATION:BCH 2201 https://plan.epfl.ch/?room==BCH%202201 STATUS:CONFIRMED END:VEVENT END:VCALENDAR
