Single-atom catalysis has generated significant interest in catalysis, particularly for environmental remediation. Pursuing desired single atom catalysts (SACs) for practical application hinges on the simplicity of synthesis methods, the choice of precursor materials, cost-effectiveness, and catalytic performance. Consequently, natural resources like biomass have been harnessed to prepare SACs, driving continuous efforts to establish controlled and scalable synthesis techniques. This comprehensive review encompasses a broad exploration of diverse synthesis methods employed for crafting SACs derived from biomass, intended for environmental catalysis by Fenton-like reactions, employing peroxymonosulphate (PMS), peroxydisulphate (PDS), or hydrogen peroxide (HO) as the oxidants. It highlights how these innovations can stimulate advancements in catalyst design, shaping the landscape of sustainable and efficient micropollutant remediation. In addition, the review summarizes the links between single-atom sites on biomass-derived SACs and catalytic mechanisms, imparting insights into the origins of catalytic activity. Finally, this review proposes the prevailing challenges and prospects in this field. It is anticipated that this review would inform the development of biomass-derived SACs and their application in environmental remediation by guiding the selection of synthesis methods and addressing the key areas for improvement highlighted in future research.
单原子催化已在催化领域引起了广泛关注，尤其是在环境修复方面。开发适用于实际应用的理想单原子催化剂（SAC）取决于合成方法的简便性、前驱体材料的选择、成本效益以及催化性能。因此，生物质等自然资源已被用于制备SAC，推动了人们不断努力建立可控且可扩展的合成技术。这篇综述全面探讨了用于制备源自生物质的SAC的各种合成方法，这些SAC旨在通过类芬顿反应进行环境催化，使用过一硫酸盐（PMS）、过二硫酸盐（PDS）或过氧化氢（HO）作为氧化剂。它强调了这些创新如何能够推动催化剂设计的进步，塑造可持续且高效的微污染物修复格局。此外，该综述总结了源自生物质的SAC上的单原子位点与催化机制之间的联系，深入了解催化活性的起源。最后，本综述提出了该领域当前面临的挑战和前景。预计这篇综述将通过指导合成方法的选择以及解决未来研究中突出的关键改进领域，为源自生物质的SAC的开发及其在环境修复中的应用提供参考。
