Hirosaki University Technology: Adsorption Material for Polar VOCs: K23-024
The formation and cleavage of reversible hydrogen bonds are key.
Volatile organic compounds (VOCs) have adverse effects on human health and the global environment. Therefore, the development of technologies to reduce emissions into the atmosphere is required. VOC adsorption using porous materials is one of the promising technologies for VOC emission reduction, and various porous materials have been developed so far. However, many of these materials excel in adsorbing nonpolar/low-polarity VOCs, and the development of materials that can selectively adsorb polar VOCs has been significantly delayed. The inventors have developed a crystalline material that can selectively adsorb and separate polar VOCs at room temperature and pressure by using hydrogen bonds that can be reversibly formed/broken. One of the materials obtained from this invention shows characteristics such as: 1) being able to adsorb twice as much amines as commercially available activated carbon, with a change in color during the process, and 2) maintaining its adsorption capacity even after repeating the adsorption and desorption of substances like acetone and ethyl acetate more than ten times. The feature of this invention lies in the ability to control the adsorption performance by adjusting the constituent molecules of the material, allowing for the provision of materials tailored to specific applications.
