Interaction of Heteroatom-Containing Organic Compounds with Bulk Nickel Alloy in a Closed Reactor System

Abstract

Catalytic chemical vapor deposition (CCVD) of different organic compounds (butyl iodide, chlorobenzene and melamine) over bulk nickel-containing items in a closed reactor system was overviewed. Scanning electron microscopy (SEM) and ferromagnetic resonance (FMR) spectroscopy were applied to characterize the samples. The process of self-disintegration of bulk metal precursor was shown to require a presence of both hydrogen and heteroatom sources in a reaction medium. Chlorobenzene and butyl iodide contain both hydrogen and halogen in an appropriate ratio. Melamine was considered as a nitrogen-containing organic compound, which is proper to synthesize the nitrogen-doped carbon nanofibers. Disintegration of nichrome wire with formation of dispersed particles catalyzing the growth of carbon nanofibers in the presence of butyl iodide was found to take place at 475°C, while in the cases of chlorobenzene and melamine the temperature required to initialize the process was 550 and 560°C, correspondingly.
