Uniform submicron hydrogenated amorphous carbon “test tubes”, both empty and containing nickel particles, were synthesized via the self-catalysis-decomposition of Ni(Hdmg) 2 (Hdmg=dimethylglyoxime anion) at 250°C. Since one end of the tubular carbon is always open but the other end is closed, they look like “test tubes”. Transmission electron microscopy images show they have an average inner...
Amorphous carbon nanotubes and Fe/C coaxial nanocables were synthesized by a solvothermal treatment of ferrocene and sulfur. In this process, the amount of sulfur played an important role in the formation of products. When the molar ratio of ferrocene to sulfur was 1:1, the products were amorphous carbon nanotubes and Fe/C coaxial nanocables. And as the ratio was decreased to 1:2, amorphous carbon...
Carbon nanotubes were synthesized via a novel route using an iron catalyst at the extremely low temperature of 180 o C. In this process, carbon suboxide was used as carbon source, which changed to freshly formed free carbon clusters through disproportionation. The carbon clusters can grow into nanotubes in the presence of Fe catalyst, which was obtained by the decomposition of iron carbonyl...
Carbon nanotubes were synthesized via a single-source precursor route at 500 o C, using iron carbonyl both as carbon source and catalyst. The X-ray power diffraction pattern indicates that the products are hexagonal graphite. Transmission electron microscope (TEM) images of the sample reveal carbon nanotubes with an average inner (outer) diameter of 30 nm (60 nm). High-resolution TEM indicates...
