| 英文摘要 | TiO2samples doped with lithium, sodium, magnesium, iron or cobalt were prepared by high-energy ball milling for different periods of time. The crystalline phase, chemical composition, crystalline size and photo-absorption were characterized by X-ray diffraction spectroscopy (XRD), X-ray photoelectron spectroscopy (XPS) and Ultraviolet visible diffuse reflectance spectroscopy (UV - Vis - DRS), Fourier transform infrared spectroscopy (FT - IR) and scanning electron microscopy (SEM). The antimicrobial properties of the modified TiO2samples were evaluated with E. coli and S.aureus assays. The results of the XRD show that the TiOSO4, Ti3O5, Li2TiO3and NaTi2O4phases appear along with Li, Na and Mg doped TiO2. However, XPS spectra indicated that Ti exists as both Ti3+and Ti4+in Na-doped TiO2samples. Ti3+, due to its narrow band gap, is highly active in promoting visible light-induced photocatalytic activity. SEM images showed that the crystalline size of TiO2is reduced and has a common-round and hexagonal plate morphology after milling. The modified TiO2samples had the best antimicrobial activities after 3 h of milling. In particular, the antimicrobial rate of TiO25% doped with transition metals (Co, Fe) reached 100% against E. coli, but the antibacterial rate against S. aureus for Co and Fe dopants was 98.4% and 98.2%, respectively. © 2017 Elsevier Ltd and Techna Group S.r.l. |
