摘　　要：逃逸到大气中的氨对人体健康和生态环境均会造成严重危害.为应对工业(固定源)和机动车(移动源)污染控制中造成的氨逃逸问题,氨选择性催化氧化技术得以有效开发,其中高效的催化剂是该技术的核心.铈基材料由于其优越的氧化还原性能、可调的表面状态和与金属容易形成强相互作用被广泛用于氨氧化催化剂的制备.本文对当前铈基氨选择性催化氧化催化剂的研究进展进行了系统总结、归纳和评述,并对该领域的未来发展方向提出了展望.The inadvertent release of ammonia into the atmosphere poses a significant threat to both human health and the environment.To mitigate NH3 slip from industry(stationary source)and vehicle(mobile source)emission control systems,the selective catalytic oxidation of NH3(NH3-SCO)technique has been developed,with catalyst efficiency at its core.Ceria-based materials,renowned for their superior redox capacity,tunable surface states,and facile formation of robust metal-support interactions,are extensively employed in crafting NH3-SCO catalysts.This paper provides a comprehensive synthesis and review of the current research progress in ceria-based NH3-SCO catalysts,offering insights into future development directions.
