Abstract

The way to produce the nanostructured carbon filaments via H2-assisted catalytic decomposition of CF2Cl2over self-organizing Ni-based catalyst has been reported. The self-organizing 6%Ni/CNM catalyst, where CNM is a carbon nanomaterial, resulted from carbon erosion of bulk Ni-Cr alloy (nichrome) in C2H4Cl2vapors was also shown to be effective for catalytic chemical vapor deposition of CF2Cl2with formation of bimodal carbon structures. It was demonstrated that interaction of nichrome with CF2Cl2/H2reaction mixture at 600 °C leads to its rapid disintegration caused by carbon erosion to form disperse active Ni-particles catalyzing the growth of carbon filaments. The resulted filamentous carbon material is characterized with high textural parameters.
