摘要

Boron-doped TiO_2 (B/TiO_2) nano-materials were synthesized by a sol-gel method and characterized by X-ray diffraction pattern (XRD), transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS), Fourier transform infrared spectrum (FT-IR) and UV-vis diffuse reflectance spectra (DRS). With the test of bacterial inhibition zone, the antibacterial properties of B/TiO_2 nano-materials on Escherichia coli were investigated. The results show that the structure of TiO_2 could be transformed from amorphous to anatase and then to rutile by increasing calcination temperature; part of the boron atoms probably have been weaved into the interstitial TiO_2 structure or incorporated into the TiO_2 lattice through occupying O sites, whereas others exist as B_2O_3. The results of antibacterial experiment under visible light irradiation show that the B/TiO_2 nano-materials exhibit enhanced antibacterial efficiency compared with non-doped TiO_2. Ultimately, the action mechanism of B/TiO_2 doping is discussed.
