Preparation of Nanosized TiO2 in the Presence of Bacteria Bacillus Paralicheniformis and its Photocatalytic Properties in the Process of Decolorization of Dyes
摘要
Nanosized TiO2 was prepared by hydrolysis of titanium tetraisopropoxide in the presence of a new bacterial strain Bacillus paralicheniformis. It was shown that the sample predominantly consisted of rutile nanoparticles with an average size of 15.4 nm. The obtained TiO2 possessed photocatalytic activity in the process of dye decolorization in effluents of a textile manufacturing industry. It was found that treatment of such solutions by the bacteria Bacillus paralicheniformis followed by irradiation in the presence of TiO2 increased the process efficiency.
