High-Yield Catalytic Synthesis of Thin Multiwalled Carbon Nanotubes. —
carbon nanotubes are synthesized with high yields of over 3000 wt%
08- 245 Multiwalled
compared to the weight of the supplied catalyst by a catalytic chemical vapor deposition
method using a FeMoMgO catalyst (H2, C2H4, and CH4, 900 °C). The catalyst is
prepared by combustion synthesis from an aqueous solution of
Fe(NO3)2, Mg(NO3)2, (NH4)6Mo7O24, and citric acid (sonication, 550 °C, grinding). The
nanotube samples are characterized by field emission scanning electron microscopy
and high-resolution transmission electron microscopy. The number of tube walls is
approximately 2—6 with the corresponding diameters of approximately 3—6 nm. —
