Operando Surface Chemistry on Copper Oxides
The chemical and electronic properties of copper, combined with its large natural abundance, lend this material to impact a wide range of technological applications, including heterogeneous catalysis. The reactivity of copper in its Cu1+ oxidation state makes this specific state relevant in various chemical reactions, but the facile redox properties of copper make the isolation of individual states for fundamental studies difficult [1]. I will present our work on model systems, including Cu2O/Cu(111) films, bulk Cu2O crystals, and copper-based mixed oxides used to study the interaction of Cu1+ with small molecules, making use of surface science techniques. Advantages and disadvantages of each system are discussed and exemplified through case studies of chemical adsorption and reactivity studies.
Bio of Dario J. Stacchiola
Dr. Dario Stacchiola is the Interface Science and Catalysis Group Leader at the Center for Functional Nanomaterials-Brookhaven National Laboratory (CFN-BNL). He obtained his B.S. degree (1997) at UNSL (Argentina) and his Ph.D. (2002) at the University of Wisconsin Milwaukee. He was a Humboldt Research Fellow at the Fritz-Haber-Institute in Berlin (2005−2007) and received a Fulbright award in 2019. He has authored over 200 peer-reviewed publications and patents. His research focuses on surface chemistry studies under operando conditions by in-situ tools, in particular structure–reactivity relationships in catalysis.
