Wood-derived catalysts for green and stable Fenton-like chemistry: From basic mechanisms to catalytic modules and future inspiration

Abstract

Most carbon-based catalysts utilized in Fenton-like systems face challenges such as structural instability, susceptibility to deactivation, and a tendency to disperse during operation. Wood-derived catalysts have garnered considerable attention due to their well-defined structures, extensive pipeline networks, superior mechanical strength, and adaptability for device customization. However, there remains a paucity of research that systematically summarizes Fenton-like systems based on wood-derived catalysts. In this review, we first summarize the structural designs of wood-derived catalysts based on nano-metal sites and single-atom sites, while also outlining their advantages and limitations applied in Fenton-like systems. Furthermore, we evaluate catalytic modules of wood-derived catalysts for scale-up and continuous Fenton-like systems. Additionally, wood-inspired catalytic materials utilizing commercial textures and their applications in Fenton-like processes are also discussed. This paper aims to comprehensively explore the fundamental mechanisms (e.g., characteristics of catalytic sites, catalytic performance, and mechanisms) of wood-based catalysts in Fenton-like chemistry, as well as their equipment designs and application scenarios, as well as providing the insights into future developments.
