Description:
A good heterogeneous catalyst for a given chemical reaction very often has only one specific type of surface site that is catalytically active. Widespread methodologies such as Sabatier-type activity plots determine optimal adsorption energies to maximize catalytic activity, but these are difficult to use as guidelines to devise new catalysts. We introduce "coordination-activity plots" that predict the geometric structure of optimal active sites. The method is illustrated on the oxygen reduction reaction catalyzed by platinum. Sites with the same number of first-nearest neighbors as (111) terraces but with an increased number of second-nearest neighbors are predicted to have superior catalytic activity. We used this rationale to create highly active sites on platinum (111), without alloying and using three different affordable experimental methods.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Calle-Vallejo, Federico -- Tymoczko, Jakub -- Colic, Viktor -- Vu, Quang Huy -- Pohl, Marcus D -- Morgenstern, Karina -- Loffreda, David -- Sautet, Philippe -- Schuhmann, Wolfgang -- Bandarenka, Aliaksandr S -- New York, N.Y. -- Science. 2015 Oct 9;350(6257):185-9. doi: 10.1126/science.aab3501.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Universite de Lyon, CNRS, Ecole Normale Superieure de Lyon, Universite Claude Bernard Lyon 1, Laboratoire de Chimie, 46 Allee d'Italie, 69364 Lyon Cedex-07, France.
