Persulfate-based advanced oxidation processes (PS-AOPs) have gained significant attention as an effective approach for the elimination of emerging organic contaminants (EOCs) in water treatment. Metal-organic frameworks (MOFs) and their derivatives are regarded as promising catalysts for activating peroxydisulfate (PDS) and peroxymonosulfate (PMS) due to their tunable and diverse structure and composition. By rationally nanoarchitectured design of MOFs-derived nanomaterial, the excellent performance and customized functions can be achieved. However, the intrinsic fine powder form and agglomerability of MOFs-derived nanomaterials have limited their practical engineering application. Recently, a great deal of efforts has been put into shaping MOFs into macroscopic objects without sacrificing the performance. This review presents recent advances in the design and synthetic strategies of MOFs-derived nano- and macroarchitectures for PS-AOPs to degrade EOCs. Firstly, the strategies of preparing MOFs-derived diverse nanoarchitectures including hierarchically porous, hollow, yolk-shell, and multi-shell were comprehensively summarized. Subsequently, the approaches of manufacturing MOFs-based macroarchitectures were introduced in detail. Moreover, the PS-AOPs application and mechanisms of MOFs-derived nano- and macromaterials as catalysts to eliminate EOCs are discussed. Finally, the prospects and challenges of MOFs-derived materials in PS-AOPs are declared. This work will hopefully guide the design and development of MOFs-derived porous materials in SR-AOPs.
