【Abstract】 To promote the applications of metal-organic frameworks(MOFs) in dyeing wastewater treatment, research progress in using MOFs for photocatalytic degradation of dyes were reviewed. Preparation methods and high designability of their space structures were introduced, and strategies for enhancing their visible photocatalytic degradation capabilities were analyzed, including the use of organic ligands modified by chromophore to construct highly visible-light responsive MOFs. The review revealed that construction of MOFs composites with high visible-light catalytic degradation efficiency was achieved by selecting highly visible-light sensitive guest molecules and making them into the inner spaces or on the surface of MOFs for post-modification. Ideas and methods to improve the recycling ability of MOFs were discussed. The degradation performance and products of dye molecules were described and analyzed. Researches on photosensitive post-modification based on highly water stable MOFs, and exploration of the combination of this material with other traditional materials and technologies, have been suggested to be the direction for promoting the applications of MOFs in dyeing wastewater treatment.更多还原
