摘　　要：目前,越来越多的国家陷入水体严重污染和水资源短缺的困难中。因此,开发高效技术去除环境废水中的污染物刻不容缓。拉瓦锡骨架材料(MIL)系列是金属有机骨架(MOFs)材料家族中的一个子类,因具有优异的结构特征和水热稳定性,在废水处理领域备受青睐。MIL系列MOFs去除水中的污染物主要有两种方式,即吸附和光催化降解。然而,原始的MIL系列材料去除污染物的效果有时候并不明显。采用各种方法(如金属掺杂、复合其他纳米材料、配体功能化、构建异质结、合成方法的改进等)对其进行改性,可对污染物的去除率达到最大化,以进一步开拓其在去除污染物方面的应用潜力。主要总结了MIL系列吸附剂、光催化剂在去除废水中污染物的研究进展。An increasing number of countries are currently suffering from terrible water pollution.Therefore,the development of efficient technologies for removal of various pollutions in water environment has significant sense for humans.Materials of Institute Lavoisier(MIL)series,an important subclass of metal-organic frameworks(MOFs)family,attract enormous interests in the field of wastewater treatment due to their extraordinary structural traits and hydrothermal stability.There are mainly two kinds of methods for MIL series MOFs to remove pollutions:adsorption and photodegradation.However,original MILs give an unsatisfactory efficiency for the pollution removal.Thus,various modification methods,such as metal doping,compounding other nanomaterials,ligand functionalization,construction of heterojunction and improvement of synthesis method,are greatly needed for further enhancing the capacity of adsorption and photodegradation,and further exploiting its utilization potentiality in removing pollutants.In this review,the research progresses of MIL-series adsorbents and photocatalysts for eliminating pollutants from wastewater were summarized.
