The invention discloses a carbon dioxide methanation catalyst and a preparation method thereof. The carbon dioxide methanation catalyst takes an aerogel oxide as a vector, an additive is added, nickel is used as an active component, the additive is alkali metal or alkali earth metal, and the aerogel oxide vector is silicon dioxide, titanium dioxide, zirconium dioxide, aluminum oxide or a compoundthereof. The catalyst comprises the following components in percentage by weight: 5-40wt.% of nickel and 0.01-30wt.% of the additive. The catalyst of the invention has high catalytic activity and stability, and can effectively catalyze carbon dioxide to be hydrogenated into methane at normal pressure under the reaction conditions that the air speed is 2000-20000h<-1>, the ratio of H2 to CO2 is 4:1, and the temperature is 300-500 DEG C. The maximum conversion rate of CO2 is higher than 90% and the maximum selectivity of CH4 is 99.9%. The preparation method of the catalyst of the invention has the advantages of simplicity, easy operation, lower cost and certain application prospects.
