Investigation of the Activity of TiO2 Nanotubes towards the Photocatalytic Degradation of Aniline

The high density and well ordered TiO2 nanotube array material was successfully application in photocatalytic degradation aniline organic wastewater analog under 254 nm, 300 nm and 365 nm UV irradiation. The results exhibited that the rate of degradation of aniline reached 99% under the concentration of aniline was 0.33 mmol•L-1, PH=7, intensity of UV irradiation was 254 nm and reaction time was 120 min. The factors that influence the rate of degradation were also investigated.
