Iron-containing catalysts of methane decomposition: accumulation of filamentous carbon

Abstract Iron-containing catalysts were tested in methane decomposition reaction at moderate temperature and pressure 1 bar in order to evaluate their catalytic properties and produce catalytic filamentous carbon (CFC). Catalyst preparation method and composition of the catalysts were found to influence their properties. The best performance was found with coprecipitated Fe-Co-Al 2 O 3 catalysts, where carbon capacity has achieved 52.4 g/g cat . TEM investigations have shown that carbon nanotubes were formed.
