摘　　要：近年来,金属有机框架(metal-organic frameworks,MOFs)所衍生的多孔碳材料得益于其优异的孔隙结构和丰富的表面官能团,对水体中的抗生素表现出优异的吸附能力。并且,MOFs基碳材料制备合成方法简单且多样。为提高该类材料的吸附性能,现今研究人员主要研究集中在MOFs前体选择、制备条件优化、微观形貌调控及表面官能团修饰等方面。文中以MOFs基碳材料含有的元素种类及含量为依据,详细列举和分析了通过不同方法制备的MOFs基碳材料,通过模型拟合深入分析其对水体中抗生素吸附过程和机理,讨论影响吸附过程的不同因素,并对制备高性能MOFs基碳材料提出了见解。In recent years,porous carbon materials derived from metal-organic frameworks(MOFs)have shown excellent adsorption capacity to remove antibiotics from water due to excellent pore structures and rich superficial functional groups.MOFs-based carbon materials can be synthesized thorough various facile methods.To improve the adsorption performance of such materials,researchers mainly focus on the rational selection of MOFs precursors,the optimization process of synthesizing conditions,the regulation of micro morphology and the modification of surface functional groups.In this review,based on the types and contents of elements contained in MOFs-based carbon materials,different kinds of MOFs-based carbon materials and their fabrication methods are summarized in details,the mechanisms of removing antibiotic from water with MOFs-based carbon materials by model fitting are analyzed,different factors affecting the adsorption process are discussed and possible ways to effectively prepare modified MOFs-based carbon materials for the adsorption of antibiotics from water are put forward.
