| Research Abstract |
The novel TiO2/sepiolite composites were prepared from two kinds of sepiolite powders with different fibrous length and 0.05~0.2wt% of TiO2 sol. The preparation process of the composites was established by investigating the raw materials and the preparation conditions. The TiO2/sepiolite composites were found to possess a very high photocatalytic activity for the decomposition of dyes, formic acid and NOx under UV irradiation. A small-scale model of water purifying apparatus was fabricated by using the TiO2/sepiolite composites and UV light or LED light. The photocatalytic activity of the apparatus was investigated to evaluate the effect of the light source.
