Abstract:The synthesis of carbon nanotubes filled with silver,
gold, and gold chloride is described.
The resulting materials have been studied by high-resolution
electron microscopy, X-ray
powder diffraction, and energy-dispersive spectroscopy (EDS). The
EDS data were obtained
using a high-resolution electron microscope equipped with a field
emission gun which allowed
for X-ray analytical data to be obtained on individual particles
located within the carbon
nanotubes using a 0.7 nm probe.
“…[34,35] The filled CNT sample is characterized by high-resolution transmission electron microscopy (HR-TEM), analytical energy-dispersive spectroscopy (EDS) and X-ray powder diffraction (XRD). Figure 1 a shows the HR-TEM image where a gold crystal is encapsulated within the CNTs.…”

Carbon nanotubes constitute a novel class of nanomaterials with potential applications in many areas. The attachment of metal nanoparticles to carbon nanotubes is new way to obtain novel hybrid materials with interesting properties for various applications such as catalysts and gas sensors as well as electronic and magnetic devices. Their unique properties such as excellent electronic properties, a good chemical stability, and a large surface area make carbon nanotubes very useful as a support for gold nanoparticles in many potential applications, ranging from advanced catalytic systems through very sensitive electrochemical sensors and biosensors to highly efficient fuel cells. Here we give an overview on the recent progress in this area by exploring the various synthesis approaches and types of assemblies, in which nanotubes can be decorated with gold nanoparticles and explore the diverse applications of the resulting composites.

“…Experimentalists were left with the cumbersome purification procedure of material where atoms were incidentally encaged during the growth process. Considerable progress was made recently at this point by discovering a possibility to fill the nanotubes with fullerenes [39] or, more generally, with matter [40]. Particular interest was directed to the filling of single wall carbon nanotubes with C 60 fullerenes in order to make so called "peapods".…”
“…About 15 mg of each non-loaded raw, oxidized and opened DWCNTs were loaded in solution with an excess of chloroquine diphosphate salt [29,30]. This anti-malarial drug is very soluble in water (100 mg mL -1 ) and extremely sensitive to sunlight.…”
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
