摘　　要：废水中的污染物由于其成分复杂、生物毒性大和难降解等特点,危害人体健康,因此,寻找开发一些能有效去除废水中的剧毒和难降解污染物的吸附剂成为亟待解决的问题。金属-有机骨架材料(MOFs)由于结构有序且多样、拓扑结构丰富、孔隙度超高、比表面积大、骨架结构稳定和易于掺杂其他组分等特点,使其在吸附领域得到了广泛的关注。多金属氧酸盐(POMs)与MOFs材料复合形成新的杂化材料POMs@MOFs,与纯MOFs材料相比不仅具有其独特的性质,同时也兼具POMs的强酸度、富氧表面和氧化还原能力,并且克服了缺点,如难以处理、比表面积小和溶解度高等特点。近年来,科研工作者发现POMs与MOFs的复合物作为吸附剂在废水处理领域具有优异的性能。本文结合本课题组的研究工作对POMs@MOFs的制备尤其是各种制备方法的优缺点进行了归纳分析,并围绕POMs@MOFs复合材料在废水处理中的应用发展进行综述,对未来研究方向和发展前景进行展望。The pollutants in the wastewater are hazardous to human health due to their complex composition,high biological toxicity and difficult degradation.Therefore,finding and developing some adsorbents that can effectively remove highly toxic and refractory pollutants in wastewater have become an urgent problem to be solved.Metal-organic frameworks(MOFs)materials have the characteristics of orderly and diverse structure,rich topology,ultra-high porosity,large specific surface area,stable framework structure and easy doping with other components,which have attracted wide attention in the field of adsorption.Compared with pure MOFs,the new hybrid materials POMs@MOFs are created by incorporating polyoxometalates(POMs)onto metal-organic frameworks(MOFs).They not only have their unique set of properties,but also combine the strong acidity,oxygen-rich surface,and redox capability of POMs.At the same time,they have overcome shortcomings of POMs and MOFs,such as difficult handling,low surface area,and high solubility.In recent years,researchers have discovered that the composites of POMs and MOFs have excellent performance as adsorbents in the field of wastewater treatment.In this paper,the synthesis and preparation of POMs@MOFs,especially the advantages and disadvantages of various preparation methods,are summarized and analyzed based on the reported researches and the works of our group.This article focuses on the application and development of POMs@MOFs in wastewater treatment.Finally,the development direction and research prospect of POMs@MOFs composite materials are also proposed.
