Abstract

A prospect of using metal dusting as an approach to synthesize self-organizing Ni-based catalysts for production of bimodal carbon materials has been discussed. Forced metal dusting of bulk Ni-M alloys driven by decomposition of chlorinated hydrocarbons led to a rapid and full disintegration of alloyed Ni-M precursors with spontaneous formation of active catalytic particles responsible for the growth of carbon filaments. Self-organizing catalysts were shown to be effective for utilization of organochlorine waste, processing of freons and various hydrocarbons into carbon nanomaterials. Secondary disintegration of metal particles resulted in the appearance of bimodal structures. The structural and morphological peculiarities of carbon nanomaterials obtained have been described.
