Carbon Nanotubes Synthesis by Chemical Vapor Deposition of Methane over Zn – Fe Mixed Catalysts Supported on Alumina
Carbon nanotubes were synthesized over a series of Zn-containing Fe/alumina catalysts by chemical vapor deposition method at two reaction temperatures of 850 and 950 °C using methane as a carbon source. Catalysts were synthesized by keeping Fe concentration constant and varying Zn concentration to study the effects of Zn. The catalysts were characterized using X – ray powder diffraction and N2 ...
متن کاملThe Impact of Cadmium Loading In Fe/Alumina Catalysts and Synthesis Temperature on Carbon Nanotubes Growth by Chemical Vapor Deposition Method
We evaluated the effect of Fe/Alumina Catalyst contained different Cadmium contents and two synthesis temperatures on producing carbon nanotubes by chemical vapor deposition of methane as a feedstock. X-ray powder diffraction (XRD), N2 adsorption-desorption, scanning electron microscopy (SEM), transmission electron microscopy (TEM), Raman spectroscopy and Thermogravimetry analysis (TGA) were u...

Using C2H2, 112 and As gases at 550'C, carbon nanotubes were fabricated on the surfaces of twosubstrates coated by nano thin layers of metal catalysts by DC magnetron sputtering. AYStamless steel andFe/CteAl, by thermal chemical vapor deposition (TCVD) The surface properties of the substrates wereparticularly investigated, and the effect of treatment of the substrates on the CNT's growth is cri...
متن کاملTemplated Growth of Carbon Nanotubes on Nickel Loaded Mesoporous MCM-41 and MCM-48 Molecular Sieves
Chemical vapor deposition was employed to synthesize carbon nanotubes with Ni-loaded MCM-41 and MCM-48 as catalysts and acetylene as precursor at 750°C. Mesoporous Ni MCM-41 and Ni MCM-48 molecular sieves were synthesized by a hydrothermal method and were characterized by XRD and N2 adsorption isotherm. The catalytically synthesized carbon materials were characterized with Raman spectroscopy, N...
متن کاملEffects of pre-treatment and plasma enhancement on chemical vapor deposition of carbon nanotubes from ultra-thin catalyst films
We report a detailed study of surface-bound chemical vapor deposition of carbon nanotubes and nanofibers from evaporated transition metal catalysts exposed to ammonia diluted acetylene. We show that a reduction of the Fe/Co catalyst film thickness below 3 nm results into a transition from large diameter (N40 nm), bamboo-like nanofibers to small diameter (∼5 nm) multi-walled carbon nanotubes. Th...
