摘要

单原子催化剂以其独特的性能和行为在环境催化领域受到越来越多的关注。近年来，关于sac在汽车尾气排放控制中的应用的报道越来越多。特别是利用SACs去除氮氧化物(NOx)引起了许多研究人员的关注。综述了NH3 (NH3 - SCR)、一氧化碳(CO-SCR)、碳氢化合物(HC-SCR)和H2 (H2 - SCR)选择性催化还原NOx的各种SACs。最后提出了活性炭在NOx排放控制领域应用面临的挑战和未来的研究方向。

Single-atom catalysts for nitrogen oxide emission control

Single-atom catalysts (SACs) have gained more and more attention due to their unique properties and behavior in the field of environmental catalysis. Recently, the number of reports on application of SACs in automobile and stationary emission control is growing. Especially, utilization of SACs in the removal of nitrogen oxides (NO_x) has attracted many researchers. This review summarizes various SACs used in selective catalytic reduction (SCR) of NO_x by NH₃ (NH₃–SCR), carbon monoxide (CO–SCR), hydrocarbons (HC–SCR), and H₂ (H₂–SCR). The challenges in application of SACs in the field of NO_x emission control and suggestion for future research are also provided.

期刊介绍： Current Opinion in Chemical Engineering is devoted to bringing forth short and focused review articles written by experts on current advances in different areas of chemical engineering. Only invited review articles will be published. The goals of each review article in Current Opinion in Chemical Engineering are: 1. To acquaint the reader/researcher with the most important recent papers in the given topic. 2. To provide the reader with the views/opinions of the expert in each topic. The reviews are short (about 2500 words or 5-10 printed pages with figures) and serve as an invaluable source of information for researchers, teachers, professionals and students. The reviews also aim to stimulate exchange of ideas among experts. Themed sections: Each review will focus on particular aspects of one of the following themed sections of chemical engineering: 1. Nanotechnology 2. Energy and environmental engineering 3. Biotechnology and bioprocess engineering 4. Biological engineering (covering tissue engineering, regenerative medicine, drug delivery) 5. Separation engineering (covering membrane technologies, adsorbents, desalination, distillation etc.) 6. Materials engineering (covering biomaterials, inorganic especially ceramic materials, nanostructured materials). 7. Process systems engineering 8. Reaction engineering and catalysis.
