【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]:Organometallic skeleton (MOFs) is a kind of porous crystalline materials with transition metal as its center and organic compounds containing hetero-atoms as ligands. Compared with other porous materials, MOFs have a wide variety of ligands, large specific surface area, adjustable pore size and special (saturated or unsaturated) metal sites, which have broad application prospects in gas storage, catalysis, adsorption and separation. In recent years, the enrichment and removal of pollutants by functionalized MOFs has become a hot topic. This is because MOFs can be functionalized to change the pore size of MOFs surface charged properties and other physical and chemical properties so as to achieve a more efficient adsorption of the target. This paper reviews the recent advances in the adsorption of drinking water pollutants by functionalized MOFs, including the types and hazards of pollutants in drinking water, the preparation methods of functionalized MOFs and the application of removal of pollutants from drinking water. The prospect of future development is also prospected.
