| description | CO<sub>2</sub> methanation was studied in the presence of nickel catalysts obtained by the solid-state combustion method. Complexes with a varying number of ethylenediamine molecules in the coordination sphere of nickel were chosen as the precursors of the active component of the catalysts. Their synthesis was carried out without the use of solvents, which made it possible to avoid the stages of their separation from the solution and the utilization of waste liquids. The composition and structure of the synthesized complexes were confirmed by elemental analysis, IR spectroscopy, powder XRD and XPS methods. It was determined that their thermal decomposition in the combustion wave proceeds in multiple stages with the formation of NiO and Ni(OH)<sub>2</sub>, which are reduced to Ni<sup>0</sup>. Higher ethylenediamine content in the complex leads to a higher content of metal in the solid products of combustion. However, different ratios of oxidized and reduced forms of nickel do not affect the initial activation temperature of nickel catalysts in the presence of CO<sub>2</sub>. It was noted that, after activation, the sample obtained from [Ni(C<sub>2</sub>H<sub>8</sub>N<sub>2</sub>)<sub>2</sub>](NO<sub>3</sub>)<sub>2</sub> exhibited the highest activity in CO<sub>2</sub> methanation. Thus, this complex is a promising precursor for CO<sub>2</sub> methanation catalysts, and its synthesis requires only a small amount of ethylenediamine. |
