Advancements in electron Rearrangement-Enhanced fenton-like catalysis of Metal-Organic Frameworks for water treatment applications

Fenton-like catalysis has emerged as a robust approach for the degradation of refractory pollutants in water treatment. Metal-Organic Frameworks (MOFs), characterized by their exceptional specific surface areas and intricate pore structures, offer abundant active sites that confer impressive Fenton-like catalytic capabilities. By strategically manipulating electron rearrangement, one can fine-tune the electronic structure and surface characteristics of MOFs, thereby enhancing their catalytic efficiency. Despite these advancements, a comprehensive overview of the role of electron rearrangement in influencing the Fenton-like catalytic performance of MOFs remains elusive. This article consolidates the current understanding of electron rearrangement in MOF-based Fenton-like catalysis. We begin by delineating the distinctive features of the electronic structures of MOFs and outlining the methods for their characterization. Following this, strategies aimed at boosting the Fenton-like catalytic performance of MOFs through electronic structure modifications are reviewed. Finally, the intricate relationship between electron rearrangement and Fenton-like reactions involving MOFs is elucidated, providing critical insights for the design of advanced MOFs architectures tailored for enhanced catalytic performance in environmental remediation.
