超声法辅助合成金属-有机骨架材料

Ultrasound-Assisted Synthesis of Metal-Organic Framework Materials

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。

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.
