摘要：

Better be capped: Ligand-capped, colloidally prepared Pt nanoparticles deposited on nanostructured iron oxide catalyze CO oxidation at unusually low temperatures when compared to the action of identical ligand-free Pt nanoparticles. The ligands efficiently modify the interaction between the metal and the iron oxide support and cause a beneficial strong metal-support interaction. As a result, the limitations resulting from CO poisoning at low temperatures can be overcome. © 2011 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
