  • Patent number: 11400331
    Abstract: A method of detoxifying a liquid chemical agent is provided using a surface-modified metal organic framework having an amine-based compound deposited on a surface and pores thereof, or bonded to the inside of a frame, wherein when the surface-modified metal organic framework comes into contact with the liquid chemical agent, a reaction with moisture in the atmosphere occurs and, the liquid chemical agent is removed through a hydrolysis reaction, thereby detoxifying chemical agents, such as nerve agents and vesicants, and assuring a high detoxification effect on liquid chemical agents at room temperature even with a small amount of the surface-modified metal organic framework.
    Type: Grant

  • Publication number: 20200114189
    Abstract: The present invention relates to a method of detoxifying a liquid chemical agent using a metal organic framework having a surface modified with a basic amine-based compound. More particularly, a surface-modified metal organic framework having the amine-based compound deposited on a surface thereof and in pores thereof or bonded to the inside of a frame is prepared, and when the surface-modified metal organic framework comes into contact with the liquid chemical agent, a reaction with moisture in the atmosphere occurs, thus removing the liquid chemical agent through a hydrolysis reaction. It is possible to simultaneously detoxify various chemical agents such as a nerve agent and a vesicant, thus assuring a high detoxification effect on liquid chemical agents at room temperature even when using a small amount thereof.

  • Publication number: 20190091503
    Abstract: Related are a chemical warfare agent (CWA) decontaminant, a method of decontaminating a CWA using the CWA decontaminant, and a product including the CWA decontaminant. The CWA decontaminant may include a metal-organic framework (MOF) including at least one metallic compound among metal hydroxide, metal hydride, metal acetate, metal methoxide, and metal oxide, and the at least one metallic compound may be dispersed either on a surface of the MOF or in pores of the MOF, or both.
