Owing to their ultrahigh surface area, regular nanostructured pores, tunable pore size, and high permanent porosity, MOFs have been widely applied for several applications, including electrochemical electrodes, biosensors, and heterogeneous catalysts. Therefore, we plan to develop novel microporous MOFs materials and applied into these emerging fields. The synthesized MOFs materials are characterized by XRD and BET surface area analysis, and the morphology will be characterized by SEM and TEM. The research proposal contains three parts of application: (1) dye-sensitized solar cells, (2) biosensing application and (3) heterogeneous solid catalysts. Each part will be developed a novel porous materials to match up the application. First, Prussian blue-based MOFs with a hollow structure are synthesized and converted to hollow nanoporous iron sulfides that could replace Pt electrode of dye-sensitized solar cells without losing the photo-electron conversion efficacy. Second, a conducting MOF named MOF-525 will be synthesized on a conducting polymer (PEDOT) to form a sensitive nanocomposite with high surface area for detecting dopamine from neutron-like PC12 cells. Third, Cu-loaded Cr-based MOFs will be synthesized through direct immobilization of Cu precursor in the synthetic condition. After calcination, a bi-metal oxide (CuCrOx) will be formed with high surface area and nanoporous structure, which will be useful as an efficient solid catalyst. A phenol hydroxylation will be performed to examine the performance of the synthesized catalysts. In this project, we not only develop a series of nanoporous MOFs materials, but also display the versatile applications.奈米孔洞材料有機金屬骨架染料敏化太陽能多巴胺感測苯酚氫氧化反應nanoporous materialsmetal-organic frameworksdye-sensitized solar cellsdopamine detectionphenol hydroxylation
