超声法辅助合成金属-有机骨架材料

摘要

In recent years,metal-organic framework materials,as a kind of novel porous materials with many functions,have become a hot research field with great potential applications,such as ion exchange,gas storage,catalysis,Medicine,selective adsorption and magnetic materials and other fields.The traditional synthesis methods of metal-organic framework,such as hydrothermal, solvent diffusion and solvothermal methods,require high synthesis temperature,solvent consumption,and time-consuming.At the same time,the metal-organic framework material synthesized by the traditional method has large crystal size and slow response speed. The metal-organic framework materials synthesized by ultrasonic assisted method can synthesize most metal-organic framework materials with high yield,and have short reaction time and high product recovery rate,and realize the regulation of the size and morphology of metal-organic framework materials,Metal-organic framework materials with different sizes and morphologies can be obtained by changing the reaction conditions using ultrasonic-assisted synthesis.%近年来，金属-有机骨架材料作为一种具有多种功能的新型多孔材料，以其巨大的潜在应用前景而成为一个热门的研究领域，例如离子交换、气体储存、催化以及在光学、医学、选择性吸附和磁性材料等领域。传统的金属-有机骨架的合成方法，如水热、溶剂扩散和溶剂热等方法，需要的合成条件温度高、溶剂消耗多、耗费时间长。同时利用传统法合成的金属-有机骨架材料晶体尺寸较大，传感响应速度慢。利用超声辅助方法合成的金属-有机骨架材料，可以高产率地合成大多数金属-有机骨架材料，且具有反应时间短、产品回收率高等特点，实现对金属-有机骨架材料尺寸和形貌的调控，利用超声辅助的合成方法，通过改变反应条件，可以得到具有不同尺寸和形貌的金属-有机骨架材料。
