Abstract
Abstract In order to obtain some noticeable microelectronic materials, the quasi-one-dimensional gold n diameters less than 50 nm were prepared by electroless plating and gold nano-particles self-assembling. The forming mechanism of gold nanowires was demonstrated, i.e. the gold nanowires could be prepared by the gold nano-particles self-assembling on the surface of carbon nanotubes (CNTs) with the presence of mercapto groups (-SH). The carbon nanotubes modified by mercapto groups were prepared by reacting with the mixed acid solution of HNO3 and H2SO4, LiAlH4, PBr3, NaHS in turn. The active mercapto groups inarched onto the surface of carbon nanotubes were also demonstrated by XPS analysis. The microstructure of gold nanowires was analyzed by TEM images and XRD pattern.
