摘　　要：CO_(2)甲烷化反应因其可以将温室气体CO_(2)转化为清洁能源(CH4)而受到广泛关注。本文介绍了CO_(2)甲烷化反应的机理与热力学研究进展,分析了CO_(2)甲烷化催化剂活性中心、粒子尺寸和载体效应对催化剂反应性能的影响规律。介绍了高熵合金、溶出型金属等新型催化剂在CO_(2)甲烷化反应中的应用,总结了影响Ni基CO_(2)甲烷化催化剂反应稳定性的2个主要因素(粒子烧结和硫中毒)以及提高Ni基催化剂抗烧结和抗硫中毒的举措(利用限域效应、添加CeO_(2)等),从而为新型CO_(2)甲烷化催化剂的研究和开发提供理论基础。最后,对CO_(2)甲烷化催化剂的研究开发进行了展望。CO_(2)methanation has attracted wide attention because it can convert CO_(2)into clean energy(CH4).This review summarized research progress of mechanism and thermodynamics of CO_(2)methanation reaction.The effects of active site, particle size and support on the performances of CO_(2)methanation catalysts were discussed, and the application of new catalysts such as high entropy alloy and dissolved metal in CO_(2)methanation was introduced. Moreover, two main factors affecting reaction stability of Ni-based CO_(2)methanation catalysts(particle sintering and sulfur poisoning) and the methods for improving anti-sintering and sulfur tolerance of Ni-based catalysts(e.g. the utilization of confinement effect, the addition of CeO_(2), et al.)were summarized, which provides theoretical basis for studying new CO_(2)methanation catalysts. Finally, the development of CO_(2)methanation catalysts is prospected.
