Physicochemical properties of carbon materials obtained by combustion synthesis of perchlorinated hydrocarbons
Journal Title: Carbon - Science and Technology - Year 2010, Vol 3, Issue 1
Abstract
We present studies on the combustion synthesis of carbon materials from several perchlorinated organic compounds: tetrachloromethane (CCl4), hexachloroethane (C2Cl6), tetrachloroethylene (C2Cl4), hexachloro1,3-butadiene (C4Cl6), hexachlorocyclopentadiene (C5Cl6). The porosity (obtained by low-temperature nitrogen adsorption), microstructure (SEM), structural arrangement (XRD and Raman spectroscopy), surface chemistry (FTIR) and electrochemical behavior (cyclic voltammetry) of the obtained carbons were investigated. The synthesized materials exhibit an ordered structure similar to carbon black. Their physicochemical properties strongly depended on the structure of the perchlorocarbon precursor. It was found that perchlorinated compounds with unsaturated bonds yielded more amorphous products. The electrochemical properties (e.g. edl capacity) depend mainly on the mesopore surface area of the carbonaceous products.
