Abstract
Metal-organic frameworks (MOFs), which are the novel porous crystalline materials constructed by coordination bonds of metal ions and organic linkers, serve as promising materials for many applications such as adsorption and separation, catalysis, chemical sensing, and solar cell; owing to their excellent porous characteristics. Recently, integration of other functional materials into MOF structure is of keen interest to express synergistic effect. Especially, the incorporation of magnetic Fe3O4 nanoparticles into MOFs enables to deliver MOF materials by external magnetic field. The magnetic manipulation can be utilized for applications such as drug delivery, catalysis, adsorption and detection. The combination of MOFs and Fe3O4 nanoparticles have been realized by direct synthesis into MOF pore or heterogeneous growth of MOF onto the surface of Fe3O4 nanoparticles. However both techniques are inevitable to generate MOFs not incorporating Fe3O4 nanoparticles.
Recently we developed a new MOF synthesis method called a spray-assisted synthesis.[1] In this method, an MOF precursor solution is sprayed and subsequently dried to enhance a self-assembly of metal ions and organic linkers; which enables to form MOF nanoparticulate powder within 10 ms continuously. Generally, one-droplet-to-one-particles conversion is considered to be the typical particle formation in a spray based material processing. We considered that addition of Fe3O4 nanoparticles into an MOF precursor solution enables to disperse Fe3O4 nanoparticles in all sprayed droplet and in all MOF particles.
Hence , in this presentation, we demonstrate the synthesis of Fe3O4/MOF nanocomposite and their dye adsorption properties.
