Advancements in design and synthesis of porous materials for selective organic dye adsorption and separation

Abstract

Against the background of rising organic dye concentrations in wastewater threatening environmental safety, urgent removal strategies are critical. This study systematically investigates the structural features of porous materials (MOFs, POFs, SOFs), their dye adsorption and separation behaviors, and influencing factors to elucidate structure–function relationships. Mechanistic insights reveal that besides intrinsic porosity, diverse non-covalent interactions significantly enhance dye adsorption efficiency and separation performance. This overview highlights advances in porous material-based dye management and proposes new avenues for structural tuning to optimize toxic pollutant removal, providing a robust foundation for next-generation environmental remediation materials.
