Various types of carbon-based and non-carbon-based catalyst supports for nitric oxide (NO) removal through selective catalytic reduction (SCR) with ammonia are examined in this review. A number of carbon-based materials, such as carbon nanotubes (CNTs), activated carbon (AC), and graphene (GR) and non-carbon-based materials, such as Zeolite Socony Mobil-5 (ZSM-5), TiO, and AlO supported materials, were identified as the most up-to-date and recently used catalysts for the removal of NO gas. The main focus of this review is the study of catalyst preparation methods, as this is highly correlated to the behaviour of NO removal. The general mechanisms involved in the system, the Langmuir-Hinshelwood or Eley-Riedeal mechanism, are also discussed. Characterisation analysis affecting the surface and chemical structure of the catalyst is also detailed in this work. Finally, a few major conclusions are drawn and future directions for work on the advancement of the SCR-NH catalyst are suggested.
本综述研究了多种用于通过氨选择性催化还原（SCR）去除一氧化氮（NO）的碳基和非碳基催化剂载体。许多碳基材料，如碳纳米管（CNT）、活性炭（AC）和石墨烯（GR），以及非碳基材料，如ZSM-5分子筛、TiO和Al₂O₃负载材料，被确定为去除NO气体的最新和最近使用的催化剂。本综述的主要重点是催化剂制备方法的研究，因为这与NO去除行为高度相关。还讨论了该系统中涉及的一般机理，即朗缪尔-欣谢尔伍德或埃利-里德尔机理。影响催化剂表面和化学结构的表征分析在本文中也有详细介绍。最后，得出了一些主要结论，并提出了SCR-NH₃催化剂改进工作的未来方向。
