Abstract
The interaction between Pt and carbon in Pt nanoparticles (NPs)–carbon nanotubes (CNTs) composite has been investigated with Pt M3-edge and C K-edge X-ray absorption near edge structures (XANES) recorded in surface-sensitive total electron yield (TEY) and bulk-sensitive fluorescence yield (FLY). XANES in TEY shows that Pt NPs on CNTs have a fcc structure and the white-line features of the XANES strongly support that the crystalline Pt NPs interact with CNTs through synergic bonding involving charge redistribution between C 2p-derived states and Pt 5d bands. Such interaction facilitates the immobilization of Pt NPs on CNT surface without generating oxygenated functional groups.
