Abstract:
In order to develop more convenient antibacterial material which can be employed to work efficiently in weak indoor light instead of any artificial light irradiation,C,Co doped mesoporous TiO2(C,Co-MTiO2) with anatase crystalline structural wall has been prepared by direct incorporation pathway by applying 1-dodecylamine as structure-directing agent and titanium tetraisopropoxide as titania source.The structures of the material are characterized by nitrogen adsorption/desorption,X-ray powder diffraction (XRD), high resolution transmission electron microscopy (HRTEM),UV-Vis diffuse reflectance spectra (UV-Vis) and X-ray photoelectron spectroscopic (XPS).The characterization results indicate that the mesoporous titania with anatase crystalline structure exhibites highly thermal stability,high specific surface area and large pore size.In addition, their antibacterial activity and bacterial solution absorbing ability without artificial light irradiation has been studied.The antibacterial test results show that not only the materials' antibacterial activity is affirmative in weak indoor light,without any artificial light irradiation,but it shows excellent absorbing ability as well.The antibacterial activity increase by 20% compared with that of Co-MTiO2.
