摘要:

金属有机骨架(MOFs)材料是一类以过渡金属为中心、含杂原子的有机物为配体、通过配位作用形成的周期性网络多孔晶体材料。与其他的多孔材料相比,MOFs配体种类繁多,比表面积极大,孔径大小可调控且具有特殊(饱和或不饱和)的金属位点,在气体存储、催化、吸附与分离等领域有广阔的应用前景。近年来,功能化MOFs对污染物的富集和去除成为学者关注的热点。这是由于通过对MOFs进行功能化修饰,能够改变MOFs的孔径大小、表面带电性质等物化性质,从而实现对目标物更高效的吸附。该文综述了近年来功能化MOFs对饮用水污染物吸附的研究进展,包括饮用水污染物的类型及危害、功能化MOFs的制备方法以及去除饮用水污染物的应用,并对今后的发展前景进行了展望。

Abstract:

Metal-organic frameworks (MOFs) are a class of periodical porous crystalline materials. They are built from organic heterocyclic compounds as ligands and transition metal ions as center via coordination interaction. Compared with other porous materials, MOFs possess a great variety of ligands, extraordinary surface areas, tunable pore sizes and special metal sites (saturated or unsaturated), which makes them many potential applications in analytical chemistry. Recent years, functionalized MOFs have drawn a growing interest in enrichment and removal of pollutants. The functionalized MOFs can promote the adsorption capacities through changing MOFs' physicochemical properties (such as pore sizes and electric charges on the surface, etc.). This review summarizes the progress in the applications of functionalized MOFs in adsorption removal of pollutants in drinking water in recent years, including the classification and harm of pollutants in drinking water, the synthesis and applications of functionalized MOFs in removal of pollutants in water, and gives the prospects in the end.
