Tailored electrocatalyst materials for renewable fuels and chemicals Maria Escudero-Escribano ICREA and Catalan Institute of Nanoscience and Nanotechnology, Spain Tailoring the structure of the electrocatalytically active sites at the atomic level is key to elucidating the design principles for the development of advanced materials for renewable energy conversion, as well as the production of green fuels and chemicals. This talk will focus on our recent work on catalyst nanomaterials for electrochemical energy conversion reactions, such as oxygen and carbon dioxide/carbon monoxide electrocatalysis. First, I will present our work toward understanding and tuning the structure-activity-stability relations for oxygen reduction [1,2] and oxygen evolution [3] for the production and utilisation of green hydrogen. Then, I will show our model studies on well-defined Cu-based surfaces to understand structure-properties relations for CO2 reduction [4-6] . We have investigated the effect of pH, specific anion adsorption and potential dependence for CO reduction on Cu single crystals [4,5] . Finally, I will discuss some strategies for selective oxidation reactions such as the partial oxidation of methane to methanol [7] . References
