The activity of low-percentage monometallic and bimetallic catalysts supported on a γ-Al2O3 support in the decomposition of methane has been studied. It was determined that bimetallic (Ni-Co/γ-Al2O3) catalyst is more active than monometallic (Ni/γ-Al2O3, Co/γ-Al2O3). The highest methane conversion and the highest amount of filamentous carbon were observed on the bimetallic catalyst. A complex of methods of scanning electron microscopy, X-ray phase analysis, temperature- programmed reduction by hydrogen has established that the addition of cobalt oxide to the composition of Ni/γ-γ-Al2O3 leads to the formation of surface bimetallic Ni-Co alloys. The formation of alloys facilitates the reduction of the catalyst and provides an increase in the concentration of active centers. These changes have a positive effect on the activity of the bimetallic catalyst.
