摘　　要：金属有机框架(MOFs)材料是由中心金属离子/金属簇与多齿有机配体通过溶剂热反应构筑的多孔结晶性固态材料。基于其多孔性、大的比表面积及中心金属节点的半导体特征,MOFs及其后修饰的复合材料在捕获和光化学反应去除水体中有机/无机污染物领域有着广泛的应用。综述了利用MOFs材料对水中染料进行光催化降解和离子光催化还原去除六价Cr(Ⅵ)研究方面的最新进展,并从金属中心/金属簇选择、配体选取,以及与其他活性物种复合进行后修饰改性的角度,提出了提升MOFs应用性能的策略,为印染废水中染料和Cr(Ⅵ)的有效去除提供借鉴。Metal-organic frameworks(MOFs)are porous crystalline solid materials constructed by solvothermal reaction of central metal ions/clusters and multi-dentate organic ligands.Based on their porosity,large specific surface area and semiconductor characteristics of the central metal nodes,MOFs and their modified compos⁃ites have been widely used in the capture and photochemical reactions removal of organic/inorganic pollutants from water.In this paper,the latest progress in the photocatalytic degradation of dyes and photocatalytic reduc⁃tion removal of hexavalent Cr(Ⅵ)ions from water by MOFs have been reviewed,and the strategies for improv⁃ing the application performances of MOFs are proposed from the aspects of metal center/cluster selection,li⁃gand selection and post-modification with other active species.It can provide reference for the effective remov⁃al of dye and Cr(Ⅵ)in printing and dyeing wastewater.
