✦ Synopsis

The structure and texture of the pyrolysis product was modified by the incorporation of FeCI, or Fe(NO,), into polyacrylonitrile (PAN). The additives were added to a PAN solution in dimethylformamide. The incorporation of FeCI, and Fe(NO,), into PAN was found to result in carbons with a smaller interlayer spacing than the carbon derived from pure PAN, as well as a larger crystallite size and a larger volume of micropores with a radius of ca. 1.8 nm. FeCl, was more effective than Fe(NO,), in the modification of the carbonization behavior of PAN.
