Dispersion of single-walled carbon nanotubes of narrow diameter distribution.
The dispersibility and bundle defoliation of single-walled carbon nanotubes (SWNTs) of small diameter (<1 nm) have been evaluated on CoMoCAT samples with narrow distribution of diameters. As previously observed by photoluminescence and Raman spectroscopy, the CoMoCAT sample exhibits a uniquely narrow distribution of (n,m) structures that remains unchanged after different dispersion conditions. ...
متن کاملHydrogen and Multiwall Carbon Nanotubes production by Catalytic Decomposition of Methane: thermogravimetric analysis and scaling-up of Fe-Mo catalysts
Fe-based catalysts doped with Mo were prepared and tested in the catalytic decomposition of methane (CDM), which aims for the co-production of CO2-free hydrogen and tubular nanostructured carbon (NC). Catalysts performance were tested in a thermobalance operating either at isothermal or temperature programmed mode by monitoring the weight changes with time or temperature, respectively, as a res...
متن کاملSynergism of Co and Mo in the catalytic production of single- wall carbon nanotubes by decomposition of CO
The catalyst composition and operating conditions for the synthesis of single-wall carbon nanotubes (SWNT) from CO decomposition have been systematically varied in order to maximize the selectivity towards SWNT. A simple quantification method based on the standard Temperature Programmed Oxidation (TPO) technique has allowed us to determine the distribution of the different forms of carbonaceous...

متن کاملControlled production of single-wall carbon nanotubes by catalytic decomposition of CO on bimetallic Co–Mo catalysts
Ž . The term ‘controlled production’ of single-wall nanotubes SWNT implies the ability to control the selectivity towards SWNT by changing catalyst formulations and operating conditions, combined with a quantitative measurement of the SWNT obtained. In this contribution, a significant advancement towards the controlled production of SWNT is reported. A family of Co–Mo catalysts has been found t...
