Abstract:

Metal-organic frameworks (MOFs) are a class of crystallized porous polymeric materials consisting of metal ions or clusters linked together by organic bridging ligands. Due to their permanent porosity, rich surface chemistries and tunable pore sizes, MOFs have emerged as one kind of important porous solid and attracted intensive interests in catalysis, gas adsorption, separation and storage over the past two decades[۱]. Controllable integration of MOFs and functional materials is leading to the creation of new multifunctional composites/hybrids, which exhibit new properties that are superior to those of the individual components through the collective behavior of the functional units. This is a rapidly developing interdisciplinary research area[۲]. MOF-based structures demonstrate various advantages such as high surface area, adjustable pore size and the simplicity of processing, tunability and use of stable alternative materials.In this work, AlO(OH)/MOF-۷۴ was synthesized. Initially we synthesized boehmite by the heat treatment method, then AlO(OH)/MOF-۷۴ composite were successfully synthesized by template free method at room temperature. The composite possess high crystallinity, porosity characteristic and good stability. The prepared materials were characterized by X-ray diffraction (XRD), Differential reflectance spectroscopy(DRS), Field Emission Scanning Electron Microscopes (FE-SEM) and Transmission electron microscopy (TEM).
