摘　　要：CO_(2)是主要的温室气体之一,发展CO_(2)化学转化技术是实现碳达标、碳中和战略目标的关键。利用CO_(2)和甲醇合成碳酸二甲酯(DMC)是近年来的研究热点,其中开发价廉、高效、高稳定性的催化剂是目前的难点。Ce O_(2)因优异的储放氧能力、丰富的氧空位及适宜的表面酸碱性,使得Ce O_(2)基催化剂得到广泛应用。综述了纯Ce O_(2)、负载型Ce O_(2)及Ce O_(2)基复合氧化物催化剂的催化性能,讨论了催化剂晶型和形貌、氧缺陷位及酸碱性对催化效率的影响,为进一步设计优化催化剂提供参考。CO_(2)is one of the main greenhouse gases.Developing the efficient CO_(2)chemical conversion technologies is the key to achieve the strategic goals of carbon peaking and carbon neutrality.The synthesis of dimethyl carbonate(DMC)using CO_(2)and methanol has been a research hotspot in recent years.However,the development of inexpensive,active and stableand catalysts is a challenge in current research.CeO_(2)-based catalysts have been widely applied due to their excellent oxygen storage and release ability,abundant oxygen vacancies and surface acid-base sites.Herein,the research progress of catalytic performance of different catalysts,including pure CeO_(2),supported CeO_(2),and CeO_(2)-based composite oxide was reviewed,with emphasis on the effects of catalyst crystal form and morphology,oxygen defect sites,and acid-base active centers.It would provide reference for the research of designing and optimizing catalysts.
