Synthesis and Characterization of Carbon Nanotubes Decorated with Gold Nanoparticles

Abstract

In presented work we report results of simple and viable method for producing Au/CNT composites.Chemical composition and crystallographic structure of the Au/CNT composites was confirmed by X-ray diffraction measurements, while transmission and scanning electron microscopy were used to characterize the morphology of nanocrystals as well as the distribution of nanocrystals in the composite.The obtained particles with relatively small diameter (less than 9 nm) were found to be spatially well dispersed on the carbon nanotubes.The density of attached Au-nanoparticles is not sufficient, and cannot be improved by simple increasing gold loading.
