- Abstract
- This article discusses catalysts for one of the environmentally friendly methods of hydrogen production (without carbon oxide emissions) based on the reaction of methane decomposition. Iron-containing systems applied to a carbon carrier — biochar — are used as catalysts. The active component (Fe) was applied by the method of incipient wetness impregnation from a solution of iron(III) nitrate nonahydrate. The catalytic systems were investigated under the conditions of the methane decomposition reaction and studied by physicochemical methods of analysis (Raman spectroscopy, X-ray phase analysis, transmission electron microscopy, elemental analysis, atomic absorption analysis). It was revealed that the catalysts are characterized by a graphite-like carbon structure in which iron-containing nanoparticles are uniformly distributed. The catalytic activity of the obtained systems in the temperature range of 500–850°C was estimated. The maximum conversion of methane is observed at a process temperature of 700°C on iron-containing biochar synthesized at a temperature of 250°C, and is 12.2%. The carbon product that is formed during the experiment is carbon nanotubes and onion-shaped carbon.
