锌铈共掺杂二氧化钛纳米材料制备与表征及其抗菌性能的研究
Preparation and Characterization of Zinc and Cerium Co-doped Titania Nano-materials with Antibacterial Activity
摘要
Abstract
Zinc and cerium co-doped titania (Zn/Ce-TiO2) nano-materials were synthesized by a Sol-Gel method at different calcination temperatures.Zn/Ce-TiO2 nano-materials were characterized by X-ray diffraction (XRD),transmission electron microscope (TEM),X-ray photoelectron spectroscope (XPS) and UV-Vis diffuse reflectance spectra (DRS).With the test of bacterial inhibition zone,the antibacterial properties of Zn/Ce-TiO2 nano-materials on E.coli.were investigated.The results show that crystallinity and the crystal phase of nano-materials are closely dependent on the calcination temperature.Zinc ions and cerium ions exist in the form of Zn2Ti3O8 and CeO2 phase,respectively.The Zn/Ce-TiO2 nano-materials synthesized exhibit enhanced antibacterial activity under visible light irradiation compared with it in the dark.Ultimately,the action mechanism of Zn/Ce co-doping is discussed.关键词
