Abstract (EN):
Ni nanoparticles and filamentous carbon were generated simultaneously by decomposing methane over Raney nickel catalyst. Nickel nanoparticles were stabilized by filamentous carbon. The Ni-filamentous carbon composite materials were tested as catalysts for the hydrogenation of ortho- and para-chloronitrobenzene, producing chloroanilines selectively (99% yield). The catalysts exclusively reduce the nitro group in chloronitrobenzenes, leaving the C-Cl bond untouched. A possible explanation for this catalyst selectivity is discussed on the basis of XPS data.
