In this work, nickel catalysts supported on high surface area mesoporous nanocrystalline gamma alumina were prepared and employed in CO methanation reaction. The γ–Al2O3 with high surface area and mesoporous structure was prepared by precipitation method and employed as support for preparation of nickel catalysts with different nickel contents. The prepared samples were characterized by XRD and BET techniques. The results showed that the optimized γ–Al2O3 possessed a mesoporous nanocrystalline structure with a high surface area of 328 m2.g–1. The catalytic results revealed that 25 wt.% Ni\Al2O3 catalyst exhibited the highest catalytic activity and showed 100% CO conversion at temperatures as low as 240°C.<\div>
