In 1890, it was discovered that carbon-containing gases decomposed on hot surfaces to form filamentous carbon. In 1953, when carbon and Fe3O4 reacted at high temperature, a filamentous structure similar to carbon nanotube was also found. Since the 1950s, the problem of carbon deposition in petrochemical plants and cold nuclear reactors, that is, the problem of carbon filament accumulation, has gradually attracted attention. In order to suppress its growth, many researches on its growth mechanism have been carried out. Carbon nanotube-like structures have been found in these carbon filaments obtained by catalytic pyrolysis of organic matter. In the late 1970s, New Zealand scientists discovered that when an electric spark was generated between two graphite electrodes, small fiber clusters were formed on the surface of the electrode. Electron diffraction measurements revealed that the walls were composed of graphite-like carbon, which was actually observed. To multi-wal |
