Synthesis of a nickel catalyst for hydrogenation of carbon dioxide to methane on a support obtained by pyrolysis of rice husk (RH) has been proposed. The original synthetic approach involves annealing of rice husk in the presence of nickel nitrate at 500–700°C, which reduces the labor, time, and energy costs of synthesis. A comparison of nickel catalysts obtained using different calcination conditions in different numbers of stages shows that the proposed method ensures an activity (18.8 h–1) comparable to the literature data. Promotion with Mn significantly improves its performance. This approach may be of great importance for the development of efficient catalysts for CO2 hydrogenation to methane and subsequent use of rice husk in catalysis.
