Photocatalysis Degradation for Aniline in TiO_2 /Bentonite by UV Irradiation

摘要

In this paper, bentonite, one of low cost natural mineral materials, was used as support of photocatalyst. After 8 hours reaction, aniline degradation yield in TiO_2/bentonite is 86. 60%, bigger than that in home-made TiO_2. If TiO_2 particle size belongs to nanometer size, degradation activity of TiO_2/bentonite increases greatly. The experiments showed TiO_2/bentonite is a latent commercial catalyst.
