Abstract

Single-atom catalysts (SACs) have attracted widespread interest due to their exceptional properties in heterogeneous catalysis. Recently, Z-scheme photocatalysts-based SACs are emerging as a versatile catalytic system for environmental applications. This review succinctly introduces the synthetic strategies for SAC-based Z-scheme photocatalysts and highlights their recent progress in advanced oxidation processes (AOPs). The applications of Z-scheme SAC-mediated AOPs in wastewater treatment are summarized, including photo-Fenton-like reactions, photocatalysis, and piezo-photocatalysis technologies. Additionally, the advantages of the Z-scheme heterojunction in photocatalysis and the corresponding Z-scheme charge-transfer mechanisms are discussed. This review offers valuable insights into the potential applications of SAC-based Z-scheme photocatalysts for environmental remediation and aims to inspire future research on advanced SACs.

用于高级氧化过程的 Z 型单原子光催化剂

单原子催化剂（SAC）因其在异相催化中的特殊性能而受到广泛关注。最近，基于 Z 型光催化剂的 SAC 正在成为环境应用领域的一种多功能催化体系。本综述简明扼要地介绍了基于 Z-scheme光催化剂的 SAC 的合成策略，并重点介绍了它们在高级氧化过程（AOPs）中的最新进展。综述了 Z 型 SAC 介导的 AOP 在废水处理中的应用，包括类光芬顿反应、光催化和压电光催化技术。此外，还讨论了 Z 型异质结在光催化中的优势以及相应的 Z 型电荷转移机制。这篇综述为基于 SAC 的 Z 型光催化剂在环境修复方面的潜在应用提供了宝贵的见解，旨在启发未来对先进 SAC 的研究。

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.
