Decoding Synergistic Pathways in Bimetallic MOFs for Advanced Oxidation Processes
Advanced Materials, EarlyView.This review presents a unified framework linking metal pairing and framework design with electronic structure, redox cycling, oxidant activation, reactive‐species generation, and catalytic performance across photocatalytic and oxidant‐based BMOF‐AOPs. The resulting design principles guide the development of hydrolytically stable and efficient BMOFs for
