Abstract:
Due to the metal ion-centered structural features, the metal-organic frameworks(MOFs) and their derivatives can be used to construct heterogeneous persulfate catalytic oxidation system. The heterogeneous persulfate activated process with low energy consumption and high efficiency has a good application prospect in water treatment. In this review, the activation of persulfate by MOFs and their derivatives to degrade refractory organic pollutants including organic dyes, environmental endocrine disruptors and antibiotics in aqueous solution were systematically presented. The effects of MOFs' and MOFs derivatives' structure and composition on the catalytic degradation of organic pollutants were discussed. It was demonstrated that the rational structure design, synthesis strategy, unsaturated metal active sites of catalysts and active species in the catalytic oxidation system played a critical role in the degradation of organic pollutants. Finally, the problems existed in the MOFs-based heterogeneous persulfate activated system were summarized and it was proposed that the construction of a new high-efficiency combined activation system and the in-depth mechanism exploration and improvement would be the focus of future research. © 2019, Chemical Industry Press.
