Abstract

Owing to their ultrahigh utilization of active sites, single-atom catalysts (SACs) with electronic features that depend on metal centers and coordination microenvironments are fantastic materials for catalyzing the advanced oxidation processes (AOPs) of peroxymonosulfate (PMS). Catalytic active sites in SACs and the corresponding mechanisms in PMS systems are essential to exploring and increasing performance. In this review, SACs for PMS-activated AOPs include Fe–SACs, Co–SACs, and other metal–SACs are introduced with their coordination microenvironments. The main mechanisms and pathways of these SACs activating PMS are further summarized and discussed. Finally, the challenges and research need of SACs are emphasized.

环境修复用过氧单硫酸盐深度氧化工艺的单原子催化剂研究进展

基于金属中心和配位微环境的具有电子特征的单原子催化剂(SACs)由于其超高的活性位点利用率，是催化过氧单硫酸盐(PMS)高级氧化过程(AOPs)的理想材料。SACs中的催化活性位点和PMS系统中相应的机制对于探索和提高性能至关重要。本文介绍了经pms活化的AOPs中主要的SACs，包括Fe-SACs、Co-SACs和其他金属- SACs及其配位微环境。进一步总结和讨论了这些SACs激活PMS的主要机制和途径。最后，强调了sac面临的挑战和研究需求。

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.
