Advanced Materials For Environmental Remediation: Metal-organic Frameworks (mofs) And Emerging Pfas Destruction Technologies

Abstract

Per- And Polyfluoroalkyl Substances (PFAS) Constitute A Large And Chemically Diverse Group Of Anthropogenic Contaminants That Have Attracted Global Concern Due To Their Extreme Environmental Persistence, Bioaccumulative Behavior, And Adverse Health Effects. The Remarkable Stability Of The Carbon–fluorine Bond Renders PFAS Highly Resistant To Conventional Biological, Chemical, And Physical Treatment Processes, Necessitating The Development Of Advanced Remediation Technologies Capable Of Both Effective Removal And Complete Destruction. In Recent Years, Metal–organic Frameworks (MOFs) Have Emerged As A Highly Promising Class Of Advanced Materials For Environmental Remediation Owing To Their Exceptional Porosity, Tunable Surface Chemistry, Modular Structural Design, And Multifunctional Capabilities. This Review Critically Examines The Role Of MOFs In PFAS Remediation, With A Particular Emphasis On Adsorption Mechanisms, Material Design Strategies, And Catalytic And Photocatalytic Degradation Pathways. In Parallel, Emerging PFAS Destruction Technologies—including Electrochemical Oxidation, Advanced Oxidation Processes, Thermal Treatment, And Hybrid Material Systems—are Comprehensively Evaluated. Key Structure, Property, Performance Relationships Governing PFAS Interactions With MOFs Are Discussed, Alongside The Challenges Associated With Material Stability, Regeneration, Scalability, And Real-world Deployment. Finally, Future Research Directions Are Proposed, Highlighting The Integration Of MOFs With Advanced Oxidation Technologies, Computational Materials Design, And Systems-level Engineering Approaches Aimed At Achieving Sustainable, Cost-effective, And Complete PFAS Mineralization.
