Due to a tremendous threat of terrorism with chemical warfare agents (CWAs) including Tabun (GA), Sarin (GB), Soman (GD) and VX, the decomposition of CWAs has received much attention for decades. CWAs are tremendously lethal chemicals that can be used as a gas, liquid, aerosol and/or powder. Although there are hundreds of known-toxic materials, only some of them are treated as CWAs. These materials are well-proven to show lethal and incapacitating effects to human. Therefore, the decomposition or detoxification of CWAs is one of the most important issues in national security and public safety. In the present time, photocatalytic reaction of phosphonates is one of the most widely used methods for CWA decomposition. They are often composed of hybrid systems containing TiO2 or ZnO photocatalyst and often show great performance for the degradation of CWAs such as soman, sarin and VX. However, they are usually encountered a great limitation in practical use, and it is highly demanded that a system can be easily used in the field. In this presentation, we like to demonstrate an effect of UV-C radiation for the decomposition of DMMP which is one of the most widely used chemical simulants. This result would show a great impact in the fabrication of personal detoxification device that can be used in the field and play an important role for national security and public safety.
