Research carried at BNL was financed by the US DOE, Office of BES (Grant No. DE-AC02-98CH10086). Some of the calculations were performed at the Center for Functional Nanomaterials at BNL. The main theoretical part was carried out by the group of J.F.S. and funded by the Ministerio de Economía y Competitividad (Spain, grants MAT2012-31526 and CSD2008-0023). Computational resources were provided by the Barcelona Centro Nacional de Supercomputación (Spain). J.E. thanks INTEVEP and IDB for grants used for the research in Venezuela.

Graphical Abstract

Wo sich Oxid und Metall treffen: Die Aktivierung eines effizienten assoziativen Reaktionspfades für die Wassergasreaktion an einer Oxid-Metall-Grenzfläche führt zu einer Erhöhung der katalytischen Aktivität von CeO_x-Nanopartikeln auf Cu(111) oder Au(111) um über eine Größenordnung (siehe Diagramm). In-situ-Experimente demonstrieren, dass eine an der Metall-Oxid-Grenzfläche gebildete Carboxyspezies das Schlüsselintermediat der Reaktion ist.
