    摘要: [Problems to be Solved] There is provided a method for production of a carbon nanotube, which allows for production of the carbon nanotube in a large scale and at a low cost.[Solution] The temperature of a catalyst loaded on a support is raised by heating the support and a raw material gas containing a carbon source is supplied on the catalyst to synthesize the carbon nanotube. The synthesized carbon nanotube is recovered, and after the recovery, the catalyst is subjected to a regeneration treatment to repeatedly utilize the support. Since the catalyst deteriorates, the catalyst is regenerated periodically or nonperiodically during the production. The regeneration treatment of the catalyst involves an oxidation treatment of the catalyst. Further, after the oxidation treatment, a reducing gas is fed to and brought into contact with the catalyst surface to reduce the catalyst. As the support, a honeycomb is used.

    摘要: The present invention provides for titanium oxide-based photocatalysts having a general formula of TiO2-X-δCXNδ and self-cleaning materials that are prepared by substituting O of pure TiO2 with C and N. A preparation method comprising a process for forming thin films of TiO2-X-δCXNδ by using gases such as Ar, N2, CO2, CO and O are used for reactive sputtering, and a process of heat treating at around 500° C., thereby crystallizing, is provided. The titanium oxide-based photocatalysts having a general formula of TiO2-X-δCXNδ and self-cleaning materials according to the present invention have a smaller optical bandgap compared to pure titanium oxides, and therefore, the photocatalysts can be activated under the visible light range. In addition, they comprise only pure anatase crystallization phase, and since the crystallized particles are small in size, the efficiency and self-cleaning effect of the photocatalysts are very high.
