Synthesis of carbon nanotubes from a chlorine-containing precursor and their properties

Catalytic performance of carbon nanotubes in H2O2 decomposition: Experimental and quantum chemical study

“…Pristine multi-walled carbon nanotubes (Chuiko Institute of Surface Chemistry of NAS of Ukraine) were synthesized by CVD method from a mixture of propylene and hydrogen using a mixed Al-, Fe-, and Mo-oxide catalyst [36]. After removing the The purified CNT samples were oxidized in 70 % HNO 3 at 373 K for 4 hrs and then washed with distilled water and NaOH solution for 12 hrs [37].…”

The synthesis of carbon nanomaterials using chlorinated hydrocarbons over a Fe-Co/CaCO3 catalyst

“…Modification of CNTs has thus led to the creation of new functional and construction materials. 11 Doping of the carbonaceous materials with non-carbon atoms, such as nitrogen, [12][13][14][15][16][17][18][19] boron, [20][21][22][23][24] sulphur, [25][26][27][28][29] oxygen [30][31][32][33][34][35][36] and halogens 11,[37][38][39][40][41][42][43][44][45][46][47][48][49][50][51][52][53][54][55] has been explored over the past two decades. Modification of the carbon surface and electronic properties has also been explored but the effect of chlorine (Cl) on the morphology of carbon nanomaterials is not well established.…”

“…41 A small number of Cl anions were also observed on the surface of the CNTs generated from dichloromethane by XPS analysis. 11 Chlorine-functionalized CNTs were also produced in the gas phase using a ball-milling method. 42 Purification of CNTs with Cl in both the liquid phase (using CCl 4 ) and the gas phase to remove metal particles showed that the gas phase was more effective, but a high concentration of Cl on the surface was loaded in the liquid phase.…”

Synthesis of bimodified carbon nanotubes?a nanocomposite material

“…The properties of CNTs can be modified by chemical means [1], in particular, by filling their cavities (fullerene-containing CNTs are believed to be potentially attractive for information storage applications), functionalizing their surfaces (fluorinated CNTs are promising components of capacitors), substituting other atoms for carbon (nitrogen-containing CNTs are of interest for creating field emitters), and intercalating atoms or molecules into the space between nested tubes (Pt-CNTs may find application in fuel-cell technology). The synthesis of nitrogen-, sulfur-, and chlorine-containing CNTs and the effect of these modifiers on the spectroscopic properties of CNTs were described in [2][3][4]. CNT/Ni materials are suitable for industrial applications in catalysis, electronic devices, and biosensors, which stimulates the development of processes for the preparation of such materials [5,6].…”
