Catalyst of Ni and Co dependencies for carbon nanotube synthesis by CVD method

In this research, the effect of catalyst type on the CNTs synthesis was investigated. The carbonnanotubes (CNTs) were produced on stainless steel substrates and two of catalyst with differentcharacteristics by using Thermal chemical vapor deposition (TCVD) method. The catalysts have theimportant role for the growth carbon nanotubes (CNTs). Acetylene gas (C2H2) diluted by NH3 wasused as the reac...

Catalytic Hydrogenation of Carbon Monoxide

The hydrogenation of carbon monoxide and carbon dioxide on various steel catalysts was studied in the temperature range of 800" to 1,300'F. and at pressures from 5 to 30 atm. The feed gases (3.75 to 20 SCFH) were passed over a catalyst bed of 1/8-h. steel balls supported in a brass-lined reactor 0.81 in. in d i m . The percentage of carbon oxides in the feed was 30% in the runs using a Hz-COZ f...

Localized synthesis of single-walled carbon nanotubes on silicon substrates by a laser heating catalytic CVD

Synthesis of high-purity single-walled carbon nanotubes (SWNTs) is demonstrated by a laser heating catalytic CVD method. This method makes it possible to produce SWNTs without the use of an electric furnace or hot filament. SWNTs were synthesized from alcohol using Fe/Co catalyst particles supported on zeolite and Mo/Co particles deposited directly on a substrate Synthesis of high purity SWNTs ...

Catalytic Oxidation of Carbon Monoxide by Cobalt Oxide Catalysts Supported on Oxidized-MWCNT

Cobalt oxide catalysts supported on oxidized multi-walled carbon nanotubes (MWCNT) for the low-temperature catalytic oxidation of carbon monoxide were prepared by an impregnation-ultrasound method. These catalysts were characterized by N2 adsorption/desorption, TEM, XRD, Raman, and H2-TPR methods. The XRD and Raman results indicated that the phase of the synthesized cobalt...

Catalytic reduction of nitric oxide by carbon monoxide.

The reduction of nitric oxide by carbon monoxide, reaction (l), mediated by metal complexes has attracted great attention recently due to its relevance to the control of air pollution and the intrinsic interest in the mechanism of N20 and C02 formation. 1-7 While a number of catalyst systems for reaction (1) have been reported, only the RhIILRhI and the PdC12CuCI2. systems rapidly catalyse the ...
