Gold Nanoparticles Self-Assembling on Surfaces of Carbon Nanotubes Modified by Mercapto Groups

Abstract:

In order to obtain some noticeable microelectronic materials, one-dimensional gold nanowires with diameters down to 50 nm were prepared by electroless plating and gold nano-particles self-assembling. The forming mechanism of gold nanowires that gold nano-particles come into being gold nanowires by self-assembling on surfaces of carbon nanotubes (CNTs) templates at presence of mercapto groups (-SH) was proved. 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 microstructure of gold nanowires was shown by TEM image and the active mercapto groups inarched onto surfaces of carbon nanotubes were demonstrated by XPS analysis.
