摘要(Abstract)：

为改善氨选择性催化还原(NH_3-SCR)脱硝催化剂的低温活性与抗中毒性能，本文综述了MnO_x、FeO_x和CuO_x基核壳催化剂的研究进展。通过系统分析核壳结构的设计策略，重点探讨了壳层包覆在保护活性位点、调控氧化还原性能以及增强界面协同作用方面的机制。研究表明，催化剂性能的提升主要归因于壳层结构对硫酸盐沉积的抑制、氧空位的有效生成以及表面酸性的合理调控。核壳结构的引入显著提高了催化剂的低温活性，拓宽了其反应窗口，并增强了抗水和抗硫性能。核壳结构被认为是构建高性能SCR催化剂的有效途径，然而目前仍面临制备工艺复杂、抗毒持久性不足等挑战。本研究为今后开发高性能核壳催化剂提供了理论依据与技术参考。
