| 摘 要： | 以钛酸四丁酯为前躯体,活性炭纤维(ACF)为载体,蔗醣为粘结剂,采用真空吸附水解法制备了TiO2/ACF催化剂.通过在TiO2/ACF表面负载上银纳米颗粒,制得Ag-TiO2/ACF光降解-抗菌复合材料.利用BET、XRD、SEM等方法对其进行了表征.研究了Ag-TiO2/ACF在光照下对亚甲基兰的降解作用和对大肠杆菌的杀灭效果.结果表明,光照2h,Ag-TiO2/ACF可以将溶液中亚甲基兰降解97%以上.当纳米复合材料中Ag含量为0.75wt%时,Ag-TiO2/ACF对大肠杆菌具有很强的灭杀作用.

| Abstract: | TiO2 supported on activated carbon fibre was prepared by means of vacuum adsorption-hydrolysis method,by using sucrose as a binder between TiO2 and ACF.The silver nanoparticles were loaded on TiO2/ACF surface by dipping method.The Ag-TiO_2/ACF was characterized by BET,XRD,and SEM.The results demonstrate that photodegradation yield of methylene blue was beyond 97% under UV-visible light irradiation for two hours.The E.coli can be completely abated by Ag-TiO_2/ACF in four hours due to the strong bacteriostati... |
