Abstract:
Carbonaceous fibers with diameters ranging from 0.1-5 microns and lengths up to several hundred microns spontaneously form during cathodic electrodecomposition of CCl4 in nonaqueous solvents CH3CN or CH2Cl2 containing tetrabutylammonium salts. The fiber morphology is dependent on current density, CCl4 concentration, and electrode surface preparation. X-ray photoelectron spectroscopic measurements revealed that the fibers consist primarily of carbon, with some nitrogen, chlorine, and oxygen impurities. X-ray and electron diffraction showed the fibers to be amorphous. jg p.2
