Fine Size Control of Platinum on Carbon Nanotubes: From Single Atoms to Clusters

Bond formation between single Pt atoms and surface thiol groups is the result of the reduction of a Pt precursor in the presence of surface‐thiolated carbon nanotubes. By setting the temperature of the following heat treatment, finely size‐controlled and monodispersed Pt clusters were obtained from...

Beschreibung
Zusammenfassung:	Bond formation between single Pt atoms and surface thiol groups is the result of the reduction of a Pt precursor in the presence of surface‐thiolated carbon nanotubes. By setting the temperature of the following heat treatment, finely size‐controlled and monodispersed Pt clusters were obtained from the dispersed single atoms (see picture).
