CO oxidation: The suitability of Pt nanoparticles capped with dodecylamine or hexanethiol ligands as oxide‐supported catalysts was investigated by FTIR spectroscopy (see picture for the hexanethiol data). It is shown that CO can penetrate the ligand shell and that the Pt nanoparticles possess activity for CO oxidation.
