摘　　要：固体氧化物电解池是一种将CO_(2)高效转化为高附加值燃料的能量转换装置,在可再生能源高效利用方面极具应用前景。用于催化CO_(2)还原反应的阴极材料是固体氧化物电解池的关键部件之一,其中具有原位金属出溶的钙钛矿材料表现出了优异的CO_(2)电解性能。本文阐述了出溶机理以及出溶在CO_(2)还原反应机制中的主要作用,综述了不同金属/合金出溶型钙钛矿阴极材料的研究进展,并对出溶型钙钛矿阴极的未来发展提出了展望。[Significance]The concentration of carbon dioxide(CO_(2))as the main greenhouse gas continues to rise in the Earth's atmosphere.Reducing CO_(2)emissions and converting them into high value-added fuels are necessary strategies to achieve the carbon peaking and carbon neutrality goals.Solid oxide electrolysis cell(SOEC)is an energy conversion device that can efficiently convert CO_(2)into high value-added fuels,which has great application prospect in the efficient utilization of renewable energy.The cathode materials used to catalyze the CO_(2)reduction reaction is one of the key components of SOEC.In addition to traditional cermet materials,various types of perovskite materials(single perovskite,double perovskite and Ruddlesden-Popper phase)are employed as new cathode materials for SOEC,due to their excellent carbon resistance,improved impurity tolerance,high redox stability and adequate ionic and electronic conductivity.However,the relatively low catalytic activity is the main factor restricting the development of perovskite cathode materials.In order to solve this problem,various methods have been adopted to improve the electrolytic catalytic activity of perovskite cathode materials,such as impregnation,A/B site doping and in-situ exsolution.Among them,the B-site doping with transition metal to promote the metal dissolution of perovskite in reducing atmosphere is considered to be an effective way to improve the electrocatalytic activity of perovskite materials.[Progress]Compared with traditional deposition technology,exsolution is an"inside-out"technology,in which the metal catalyst migrates from the solid lattice and segregates or aggregates on the substrate surface to produce precipitation,namely,the migration of metal ions to the surface of perovskite and the phase transformation into a metal phase.The exsolution technology of perovskite-type materials(ABO3)is considered to be an effective approach to improve the catalytic activity of perovskite-type materials through nanoparticle modification.Usually,transit
