金属有机骨架及其衍生材料活化过硫酸盐在水处理中的

金属有机骨架材料（MOFs）具有以金属离子为中心的结构特征，因此利用MOFs及其衍生材料可构建非均相过硫酸盐催化氧化体系，该体系能耗低且高效，在水处理中具有良好的应用前景。本文综述了MOFs及其衍生材料活化过硫酸盐处理水中难降解有机污染物（包括有机染料、环境内分泌干扰物和抗生素）的研究现状，探讨了不同组成及结构的MOFs及MOFs衍生材料对催化降解水中有机污染物性能的影响，指出MOFs及其衍生材料的结构设计、合成策略、不饱和的金属活性位点以及反应体系中的活性物质等是体系催化降解能力的重要影响因素。最后总结了目前基于MOFs材料活化过硫酸盐作为一种新型的高级氧化技术在水处理应用研究中存在的问题，并提出新型高效联合活化体系的构建及活化作用机制深入的探索和完善是今后研究的重点。

Progress in the applications of metal-organic frameworks and derivatives activate persulfate in water treatment

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.
