Electric double layer capacitance of highly pure single ...

2002-7-1 · The double layer capacitance of highly pure single-walled carbon nanotubes (SWCNTs) prepared by the HiPco™ process was measured in 1.0 mol dm −3 LiClO 4 /propylene carbonate solution. The unpurified SWCNT electrode was mainly composed of a bundle structure of SWCNTs with around 1.0 nm tube diameter, small amount of amorphous carbons, and Fe catalyst particles.

Modeling of the HiPco process for carbon nanotube ...

The high-pressure carbon monoxide (HiPco) process, developed at Rice University, has been reported to produce single-walled carbon nanotubes from gas-phase reactions of iron carbonyl in carbon monoxide at high pressures (10-100 atm). Computational modeling is used here to develop an understanding of the HiPco …

2020-9-24 · Fig. 3. Schematics of the CVD apparatus. High Pressure Conversion of Carbon Monoxide (HiPco) The method called high pressure conversion of carbon monoxide (HiPco) is employed to produce SWCNTs by continuously flowing CO gas phase (i.e. the carbon feedstock) and Fe(CO) 5, the catalyst precursor [25], through a heated reactor (see Fig. 4).The average diameter of HiPco SWCNTs is …
