A study on the effect of high-temperature treatment has on the thermal stability of Sibunit, a graphite-like carbon material, under the conditions of an oxidative environment depending on the presence of the active component (Pt, Pd or Ru) has been performed. Thermal analysis results show that preliminary high-temperature treatment of Sibunit raises the temperature of the onset of carbon oxidation. It is found that keeping Ru/Sibunit samples in a nitrogen–air mixture (1 : 1) for 4 h at a temperature of 400°C results in partial destruction of Sibunit’s pyrocarbon framework and an increase in the average size of Ru particles. Using Ru as an example, it is shown that ruthenium catalysts can effectively oxidize CO at temperatures no higher than 200°C and withstand overheating up to 400°C with no appreciable loss of activity
