Dye wastewater is an universal problem that restricts sustainable development. Adsorption is an effective technique for water purification due to high efficiency, economic feasibility and operational ease. Metal-organic frameworks (MOFs) as adsorbent has attracted great attention due to exceptionally high porosity, compositional and structural diversity, and highly tunable pore shape/size and surface functionality. This review focused on recent progress in different typological and structural MOFs as superior adsorbents for the efficient removal of toxic dyes. Optimized, modified, defective, compositive and derived MOFs could improve the adsorption performance of MOFs. In particular, some MOFs-based adsorbents with special structure were concerned. The interactions between dyes and MOFs-based materials are systematically summarized, including adsorption performance, kinetics, thermodynamics and mechanism. Finally, we propose our personal insights to the development of MOFs-based adsorbent better used for environmental pollution management.
