| Abstract: | The attachment of gold nanoparticles (NPs) onto chemically functionalized multiwalled carbon nanotubes (MWCNTs) by ion pairing interaction is reported. The structure and composition of the resulting gold NP/MWCNT hybrids were characterized by transmission electron microscopy, X-ray diffraction, and X-ray photoelectron spectroscopy. A high-density of gold NPs was homogeneously dispersed on the modified MWCNTs. The hybrids show characteristic plasmon absorption of gold NPs in the UV-visible spectrum and good electrochemical properties. |
