Abstract
TiO 2/nylon fabrics were investigated for methanol degradation under UV light irradiation. TiO 2 Degussa P-25 was supported on nylon by immersing the nylon in sol–gel TiO 2 and silicone. The TiO 2 layers on the nylon were explored as a function of the time of immersion, impregnation agent and the type of nylon fabric used. The energy diffuse spectroscopy (EDS) and infrared spectroscopy (ATR-FTIR) confirmed the presence of TiO 2 bonded to the nylon fabrics. Optical microscopy (OM) and scanning electron microscopy (SEM) show a more uniform distribution of TiO 2 on nylon fabrics prepared by immersion in sol–gel as compared to the silicone method. The most suitable photodegradation of gaseous methanol by TiO 2/nylon samples was obtained by sol–gel samples prepared by 24 h immersion time.
