Synthesis carbon nanohorns

WebMar 31, 2004 · A method of synthesizing bulk amounts of single-walled carbon nanohorns (SWNHs) on a significant low-cost basis is proposed based on the ‘arc in water’ method with N 2 injection into the arc plasma. It is elucidated that rapid quenching of the carbon vapour in an inert gas environment is necessary to form the delicate SWNH structures. WebSingle-walled carbon nanohorns are made of graphene sheets with long cone-shaped tips with the diameters of 2-5 nm and the length of 40-50 nm. Thousands of carbon nanohorns form spherical aggregates of about 100 nm in diameter. ... Chemical Synthesis, Chromatography, Analytical and many others.
