Diameter-controlled synthesis of discrete and uniform-sized single-walled carbon nanotubes using monodisperse iron oxide nanoparticles embedded in Zirconia nanoparticle arrays as catalysts

Article Abstract:

Binary arrays, that were composed of monodisperse zirconia nanoparticles with a particle size of 2.0 nm and monodisperse iron oxide nanoparticles with particles sizes of 3.3 and 1.8 nm, are used for synthesis of discrete single-walled carbon nanotubes (SWNCTs) with uniform diameters of 3.0 and 1.8 nm. The results clearly demonstrate that the prevention of the agglomeration of iron oxide nanoparticles by mixing with zirconia nanoparticles was critical for the synthesis of uniform-sized SWNCTs.

Synthesis and characterization of highly ordered Co-MCM-41 for production of aligned single walled carbon nanotubes (SWNT)

Article Abstract:

Highly ordered cobalt substituted MCM-41 samples were synthesized and characterized for application as catalytic templates for producing aligned single walled carbon nanotubes (SWNT). The growth of SWNT in the pores of Co-MCM-41 was confirmed by Raman spectroscopy and TEM. d

Synthesis of single-walled carbon nanotubes in flames

Article Abstract:

The synthesis of single-walled carbon nanotubes (SWNTs) in sooting flames is presented. A viable path towards low-cost large-scale synthesis, which is lacking in arc- and laser-based SWNT synthetic techniques, is offered.
