Abstract

The interaction of 1,2-dichloroethane (DCE) vapors with bulk NiCr alloy resulting in complete metal wastage with the formation of carbon nanofibers (CNFs) has been described from mechanistic point of view. The genesis of surface transformations of the bulk NiCr alloy exposed to corrosive reaction mix Ar/H2/DCE at 550 C was studied by AFM, SEM and TEM techniques. The mechanism of metal dusting in aggressive reaction media was suggested. The observed process has been considered as a way to produce the self-organizing Ni/CNF catalyst which is effective for further decomposition of chlorinated hydrocarbons leading to nanostructured carbon product.
