摘要
以钛酸四正丁酯、氯化锌、冰醋酸等为原料,采用水热法制备了ZnO/TiO_2复合光催化剂。通过X-射线衍射仪(XRD)、扫描电子显微镜(SEM)、能谱仪(EDS)对所制备纳米复合材料的物相组成以及微观形貌进行了表征。采用牛津杯法以抑菌圈大小为评价指标,研究了不同工艺条件下制得的ZnO/TiO_2复合材料对大肠杆菌、金黄色葡萄球菌、根霉、黑曲霉抗菌性能的影响。研究结果表明,重量比为1:10的ZnO/TiO_2复合材料具有良好的抗菌性能。
The composite photocatalyst of ZnO/ TiO2 were synthesized by the hydrothermal method using tetrabutyltitanate,zinc chlorideand aceticacid as raw materials. The effects of reactant concentration on the morphologyand structural were investigated by XRayDiffraction(XRD),Scanning Electron Microscope(SEM),Energy Dispersive Spectrometer(EDS). With the antibacterial circlesize as the evaluation pointer by Oxford Cup method,the antibacterial properties of ZnO/ TiO2 nanocomposite powders on Escherichiacoli,Staphyloccocus aureus,Rhizopus nigricans and Aspergullus niger were studied which prepared in different process conditions,respectively. The results showed that the antibacterial properties of the ZnO/ TiO2 nanocomposite powders was better than theothers when the weight ratio of ZnO to TiO2 was 1 ∶10.
