Many routes have been developed for the synthesis of carbon nanotubes, but their assembly into continuous fibers has been achieved only through postprocessing methods. We spun fibers and ribbons of carbon nanotubes directly from the chemical vapor deposition (CVD) synthesis zone of a furnace using a
Double-wall carbon nanotubes (DWNTs) have been selectively synthesized over Fe/Co loaded mesoporous silica by catalytic chemical vapor deposition of alcohol. Several silica materials with desired pore diameter and morphology have been investigated for the DWNT growth.

Chemical vapor deposition is a classical deposition method to produce high quality and high-performance solid thin film materials, such as carbon nanotube, graphene, diamond, and metal [15, 16]. Therefore, this method was widely employed to grow carbon materials on the surface of clay minerals by chemical reaction and/or decomposition of
