Pseudocapacitive Effects of N-Doped Carbon Nanotube Electrodes in Supercapacitors
Nitrogenand micropore-containing carbon nanotubes (NMCNTs) were prepared by carbonization of nitrogen-enriched, polymer-coated carbon nanotubes (CNTs), and the electrochemical performances of the NMCNTs with different heteroatom contents were investigated. NMCNTs-700 containing 9.1 wt% nitrogen atoms had a capacitance of 190.8 F/g, which was much higher than that of pristine CNTs (48.4 F/g), de...
متن کاملDispersing as-prepared single-walled carbon nanotube powders with linear conjugated polymers.
Suitably modified linear conjugated poly(arylene ethynylene)s are able to assist effective debundling and dispersion of crude as-prepared single-walled carbon nanotube powders in organic solvents, the dispersion of which is effected via a surface coating mechanism and, to some extent, in a size-selective fashion.
متن کاملA Novel Dispersing Agent for Carbon Nanotubes
Since the discovery of carbon nanotubes (CNTs), researches of field emission display (FED) have been mainly focused on it, because of their high-aspect configuration, low work function, high mechanical stability and high conductivity. For CNTs to become a viable engineering material for FED applications, efficient assembly and integration processes for large size are required that are currently...
متن کاملElectrochemical purification of carbon nanotube electrodes
We present a fast and effective electrochemical method to purify random networks of single-walled carbon nanotubes (SWCNTs) that leads to total removal of metal catalyst without apparent detrimental effect on the electrochemical properties of the electrodes. The efficiency of the electrochemical purification has been compared with that of conventional chemical purification (acid washing). The d...
متن کاملElectrochemistry of Carbon Nanotube Composite Electrodes
Carbon nanotubes can be considered as molecular-scale wires with high mechanical strength and different electronic properties (metallic, semiconducting or semimetallic) depending mainly on the tube symmetry [14]. These properties have been utilized for the development of various electrochemical sensors for monitoring gases as NO2 or NH3 [5], the oxidation of biomolecules (dopamine, ascorbic aci...
