摘要：Two new metal-organic frameworks (MOFs) [Co(AIA)(3-bpdh), Mn(AIA)(3-bpdh)], featuring 2-dimensional layer network topologies are successfully assembled by the solvent diffusion method as CoII and MnII isostructural MOFs, hereafter, 1Co and 1Mn. Moreover, a series of micro-crystals of these two kinds of MOFs with different morphologies and sizes are also obtained by adjusting the synthesis systems. Interestingly, one MOF exhibits selective catalytic oxidation properties for the degradation of malachite green dye, whereas the other MOF shows corresponding properties for methylene blue. In addition, a detailed possible oxidation catalytic mechanism is proposed. This work highlights that MOFs are functional materials for selective dye degradation and demonstrates that metal ion replacement is an efficient way to regulate MOFs for deserving applications.
