摘要：

We focus on the sol-gel synthesis of N-doped TiO2 at various ammonia/TTIP molar ratio (0.0 similar to 3.0) and calcination temperatures (400 similar to 800 degrees C). Samples were analyzed by XRD, UV-Vis, BET and DTA-TG in order to understand the characteristics of N-doped TiO2. The photocatalytic oxidation reaction activity of N-doped TiO2 were evaluated for the decomposition of the ethylene under the visible light irradiation. The result indicate the major peak of crystallite plane of anatase and rutile for temperatures showed 400 degrees C and 700 degrees C, respectively. The N-TiO2 samples revealed the significant red shift of the absorption edges. When the temperature increasing, the percentage of weight (%) displayed decreasing. Lastly, the N-TiO2 exhibited much higher photocatalytic activity of photodegradation of ethylene than pure TiO2 under visible light illumination.
