Formation of Y-junction carbon nanotubes by catalytic CVD of methane

Abstract

Y-junction carbon nanotubes were grown by catalytic CVD of methane at 700 {ring operator} C on NiO-CuO-MoO(7:2:1) (w/w/w)/SiO 2 catalyst. For comparison, NiO-CuO(8:2) (w/w)/SiO 2 and NiO-MoO(8:2) (w/w)/SiO 2 catalysts were tested for carbon nanotube formation. TEM analysis indicates that no Y-junction structures were formed with the latter two catalysts. This finding elucidates why the addition of a small amount of MoO to NiO-CuO/SiO 2 catalyst is crucial for enhancing the formation of Y-junction carbon nanotubes. © 2006 Elsevier Ltd.
