Abstract

In this study, copper-doped zinc oxide with oxygen vacancies reduced by sodium borohydride (Cu-ZnO-R) was synthesized in the forms of nanoparticles and nanorods. The characterization by X-ray diffraction (XRD), scanning electron microscopy (SEM), X-ray photoelectron spectroscopy (XPS), electron spin resonance (ESR), and transmission electron microscopy (TEM) provided evidence for the successful synthesis of copper-doped ZnO nanorods with reduced oxygen vacancies. The photocatalytic antimicrobial tests against Escherichia coli, Staphylococcus aureus and Thielaviopsis basicola were performed. The disinfection results showed that the introduction of oxygen vacancies and copper doping significantly enhanced the disinfection efficiency of the nanorods under both illuminated and dark conditions.

氧空位工程铜掺杂氧化锌纳米颗粒和纳米棒的抗菌活性

本研究以纳米粒子和纳米棒的形式合成了硼氢化钠还原氧空位的铜掺杂氧化锌（Cu-ZnO-R）。通过x射线衍射（XRD）、扫描电子显微镜（SEM）、x射线光电子能谱（XPS）、电子自旋共振（ESR）和透射电子显微镜（TEM）对ZnO纳米棒进行了表征，为成功合成氧空位减少的铜掺杂ZnO纳米棒提供了证据。对大肠杆菌、金黄色葡萄球菌和基氏蒂拉维opsis进行了光催化抑菌试验。消毒结果表明，在光照和黑暗条件下，引入氧空位和铜掺杂均显著提高了纳米棒的消毒效率。
