【摘要】 通过简单的溶剂热法制备了铝基金属有机骨架MOF-303材料。利用X射线衍射仪、扫描电子显微镜、傅里叶变换红外光谱仪、全自动比表面积和孔隙度分析仪对MOF-303材料的结构进行了表征。对以MOF-303材料构建的石英晶体微天平传感器进行湿度敏感性能测试，结果表明，基于MOF-303材料的传感器在较宽的湿度范围内(3.39%～97.9%RH)表现出优异的湿敏性能，尤其是在3.39%RH低湿度条件下具有高达3 200 Hz的响应值，在极低湿度环境检测方面显示出应用潜力。此外，还对MOF-303材料的湿度敏感机制进行了探究。更多还原

【Abstract】 Aluminum based metal-organic framework MOF-303 was prepared by a facile solvothermal method. The structure characteristics of MOF-303 were investigated by X-ray diffractometer, scanning electron microscope, Fourier transform infrared spectrometer, and automatic specific surface area and porosity analyzer.Aquartz crystal microbalance sensor based on MOF-303 was tested for humidity sensing properties. The experimental results showed that MOF-303 sensor had an excellent sensing property over a wide humidity range(3.39% to 97.9% RH). Especially, the MOF-303 sensor exhibited a response value up to 3 200 Hz at 3.39% RH, providing an application potential in the detection of extremely low humidity environment. In addition, the humidity sensing mechanism of MOF-303 was further explored.更多还原
