摘　　要：综述了国内外CO甲烷化催化剂的研究现状,重点介绍了CO甲烷化Ni基催化剂的载体、助剂和催化机理等方面的研究进展。关于载体的研究由Al2O3转向ZrO2,助剂从碱土金属和稀土金属向过渡金属元素转变,并在催化机理的研究中引入密度泛函理论,考察反应过程中生成的活性中间物种对催化活性的影响,以期改进这类催化剂,促进其工业应用。以新型载体负载Fe等多金属催化剂将是未来CO甲烷化催化剂发展的新方向。Ni-based catalysts for CO methanation were introduced, especially focused on supports, promoters and catalysis mechanism. It was found that ZrO2 was used as support instead of Al2O3, while the promoters covered not only alkaline earth, lanthanon but also transition metals. As to the catalytic mechanism, density functional theory was introduced to investigate effect of intermediate species on activities of the catalysts. In conclusion, multi-metal catalysts such as Fe-Ni alloy supported on novel support are a prospective subject for CO methanation.
