Catalytic synthesis of carbon nanotubes having fullerene-like structure applying supported transition metal/zeolite catalysts is introduced in this work. Decomposition of unsaturated hydrocarbons was carried out under relatively mild conditions in a fixed bed flow reactor. The quality of the carbon deposit was characterized by means of transmission electron microscopy. For the separation of carbon...
Carbon nanotubes were produced in large amounts by catalytic decomposition of acetylene in the presence of supported Co and Fe catalysts. The influence of various parameters such as the way of catalyst preparation, the nature of the support, the size of active metal particles, and the reaction conditions on the buckytube formation was studied. The process was optimized towards the large-scale production...
The catalytic production of carbon nanotubes was investigated using various iron catalysts. Catalyst samples were made by different preparation methods in order to improve both the quality and the quantity of as-prepared carbon nanotubes. The catalysts were tested in the decomposition of different hydrocarbons in the temperature range 650-800°C using either fixed bed flow or fluidized bed reactor...
