NH3选择性催化还原NOx (NH3-SCR)是一种广泛应用于以燃煤电厂为代表的固定源和以柴油发动机为代表的移动源NOx排放控制的技术。近年来，氧化铈由于具有优异的氧化-还原、储氧和表面酸性等特性而在NH3-SCR催化剂研究中受到广泛关注。本文系统综述了氧化铈用作NH3-SCR催化剂载体、助剂和主催化组分的相关研究，并对该领域未来可能的研究方向进行展望。

The selective catalytic reduction of NOx with NH3 (NH3-SCR) is one of the widely used NOx control strategies for stationary sources (particularly for power plants) and mobile sources (particularly for diesel vehicles). The application is aimed at meeting the increasingly stringent standards for NOx emissions. Recently, ceria has attracted much attention for its applications in NH3-SCR catalysts owing to its unique redox, oxygen storage, and acid-base properties. In this article, we comprehen-sively review recent studies on ceria for NH3-SCR catalysts when used as support, promoter, or the main active component. In addition, the general development of ceria for NH3-SCR catalysts is dis-cussed.
