The presence of Ni improved the carburization extent of Mo-species, resulting in increased catalytic activity and selectivity for the catalytic CO₂ methanation reaction. Carburization generally enhances the basicity of the materials and thus CO₂ absorption on their surface. At 300ˇăC, the conversions of CO₂ for the reduced Ni-Mo/Al₂O₃ catalyst and Ni-Mo₂C/Al₂O₃ catalysts were 5.3% and 13.8% respectively with a corresponding selectivity in CH₄ of 10.0% and 98.1%, respectively. %K CO< %K sub> %K 2< %K /sub> %K Methanation %K Carbide Catalysts %K Nickel %K Molybdenum %U http://www.scirp.org/journal/PaperInformation.aspx?PaperID=80417
