金属有机框架材料在化学战剂降解中的应用研究进展

Advance on the application of MOFs in the degradation of chemical warfare agent

化学战剂是一类毒性大、作用速度快、毒性持久、能大规模毒害敌方的化学物质,因为对人体健康和环境存在严重危害,所以开发能快速降解化学战剂的材料在军事和民用领域具有重要意义。金属有机框架材料是一种由金属离子或金属离子簇与有机配体通过配位方式形成的多孔晶体材料,具有比表面积大、孔隙率高、结构可调、易于修饰等优点,优异的吸附性能和催化性能使得金属有机框架材料在化学战剂降解领域具有广阔的应用前景。综述了近年来金属有机框架材料在降解化学战剂方面的研究进展,并展望了其未来的发展前景。

Chemical warfare agents are a class of chemicals with high toxicity,fast action,long-lasting toxicity,and large-scale poisoning of the enemy.Because of its serious harm to human health and environment,the development of materials capable of rapidly degrading chemical warfare agents has great significance in both military and civilian applications.Metal-organic frameworks(MOFs)are porous crystalline materials comprised of metal nodes/clusters and organic linkers,have the advantages of high surface area,high porosity,adjustable structure and easy to modification.MOFs has a promising application in degradation chemical warfare agents due to its superior adsorption and excellent catalytic performance.The advanced application of MOFs to degrade chemical warfare agents was reviewed.Moreover,the future development was also discussed.
