Dye adsorption of single crystalline macro-microporous MOF

Metal-organic frameworks (MOFs) in dye adsorption fields have been extensively studied due to it full of micropores. However, their micropores limit the materials, the speed of adsorption was also restricted. In this paper, we synthesized the single crystalline macro-microporous MOF through hard template method and compare its Rhodamine B adsobtion speed with traditional microprous MOF's, the result shows that the structure of macroporous significantly improved the dye adsorption ability of MOF.
