Surface Chemistry on Copper Oxides — •Dario Stacchiola — Brookhaven National Laboratory, Upton NY, 11720, USA

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. 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 in-situ surface science techniques. Advantages and disadvantages of each system are discussed and exemplified through case studies of chemical adsorption and reactivity studies
