| Abstract: | Objective]The aim was to fabricate more convenient antibacterial material which could be employed to work efficiently without both artificial and solar light irradiation.Method]Co doped mesoporous TiO2 composite materials with anatase crystalline structural wall were prepared,and its structure of the materials was characterized by nitrogen adsorption/desorption,and XRD spectroscopy.Besides,their antibacterial activity and bacterial solution absorbing ability without artificial and solar irradiation was studied.Conclusion] The antibacterial test results showed that not only the composite materials' antibacterial activity is affirmative without artificial and solar light irradiation,as the antibacterial circle toward E.coli indicated,but also it showed excellent absorbing ability as well.Conclusion] The study will provide reference for studying other metal ion doped mesoporous materials. |
