摘　　要：通过Zn(NO3)2.6H2O和NaOH的醇溶液制备ZnO,利用XRD和TEM对产物进行表征,产物为具有较高的结晶度和纯度的ZnO纳米棒,直径约为30nm,长度约为130～500nm。取市售ZnO和产物,采用抑菌圈法对3种常见致病菌作药物敏感试验,并测定了产物对金黄色葡萄球菌的最小杀菌浓度(MBC)。结果表明,产物与市售ZnO试剂均对大肠杆菌不敏感,对金黄色葡萄球菌和白色念珠菌有不同程度的敏感,且产物比市售试剂抑菌效果更为明显,产物对金黄色葡萄球菌的最小杀菌浓度(MBC)为1.5%。ZnO nanorods were prepared by a simple alcohol thermal method with a reaction system composing of Zn （NOa）2--CHa CH20H--NaOH. The phase composition and morphology of the products were characterized by X-ray dif- fraction（XRD） and transmission electron microscopy（TEM）. The results showed that ZnO nanorods with a diameter about 30nm and a length of 130-500nm could be prepared by this method. The antibacterial properties of the products and com- mercial ZnO were investigated by the inhibition zone method. Furthermore, the minimum bactericidal concentration（MBC） of ZnO nanorods on staphylococcus aureus was also examined. The antibacterial experiments showed that the samples and commercial ZnO reagents were sensitive to staphylococcus aureus and Candida albicans,and the antimicrobial capacity of the nanorods was much better than the commercial ZnO. The MBC of ZnO nanorods on staphylococcus aureus was 1.5%.
