TiO2 nanomaterials were successfully synthesized by sol gel method. TiO2 nanomaterials were characterized by X-ray difraction (XRD), Scanning electron microscopy (SEM), N2 adsorption–desorption and UV-Vis DRS. The SEM images of TiO2 samples showed the nanoparticle size of 20–30 nm and high specific surface area of 139 m2g-1. The TiO2 nanomaterials were used as the degradation of dimethyl 4-nitrophenyl phosphate (DMNP) chemical warfare agent emulator. The TiO2 nanomaterial exhibited highly catalytic performance of DMNP degradation and the conversion reached to the value of 96.14 %, after 120 min of reaction. The TiO2 photocatalyst performs three processes simultaneously, such as adsorption, hydrolysis and photocatalysis, so the DMNP treatment efficiency are greatly enhanced. The DMNP reduction efficiency of TiO2 catalyst reached over 90% after 4 reaction cycles.
