Abstract

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.

副青衣芽孢杆菌存在下纳米TiO2的制备及其在染料脱色过程中的光催化性能
在一种新型菌株副青衣芽孢杆菌的存在下,利用四异丙醇钛水解制备了纳米TiO2。结果表明,样品主要由金红石纳米颗粒组成,平均尺寸为15.4 nm。所得TiO2在纺织工业废水染料脱色过程中具有光催化活性。研究发现,用副青衣芽孢杆菌(Bacillus paricheniformis)处理这些溶液,然后在TiO2存在下进行辐照,可以提高工艺效率。
