Abstract Decomposition and degradation issues of chemical warfare agents (CWA) that have an organophosphate structure are getting important challenges since most CWAs can disrupt the balance of the sympathetic and parasympathetic autonomic nervous system inside DNA. Methyl paraoxon that has organophosphate functional group is one of simulants among nerve agents such as tabun, sarin, and soman. Until now, for the decomposition and degradation of nerve agents, TiO2 has been mostly studied and used as a photo catalyst. However, the use of the TiO2 has a limited use since a band gap of TiO2 is too much large to efficiently absorb a visible light or solar irradiation. In this study, we like to report newly synthesized two different black and blue TiO2s, which can absorb visible and infrared lights. Finally, we like to report the decomposition of methyl paraoxon under solar light with UV-vis, FT-IR and NMR spectra..
