Abstract: In this work, the approach of Reactions under Autogenic Pressure at Elevated Temperature (RAPET) was applied to study the decomposition of different halogen-containing organic compounds over bulk Ni and NiCr alloy (nichrome wire). Method of ferromagnetic resonance (FMR) was shown to be rather informative for in situ studying of catalytic corrosion processes taking place on the surface of the alloy during interaction with halogenated hydrocarbons which is accompanied by the formation of nickel nanoparticles. Highly organized submicron structures of halogenated Ni-species was found to appear at the RAPET conditions when the closed reaction volume contains both hydrogen and halogen sources. Such species were shown to be stable in a narrow range of temperature. The obtained metastable intermediates were characterized by scanning electron microscopy.
