The present study reported biofabrication of flower-like SnO nanoparticles using leaf extract. The study focused on the physicochemical characteristics of the prepared SnO nanoparticles and its activity as photocatalyst and antibacterial agent. The characterization was performed by XRD, SEM, TEM, UV-DRS and XPS analyses. Photocatalytic activity of the nanoparticles was examined on bromophenol blue photooxidation; meanwhile, the antibacterial activity was evaluated against , and . XRD and XPS analyses confirmed the single tetragonal SnO phase. The result from SEM analysis indicates the flower like morphology of SnO nanoparticles, and by TEM analysis, the nanoparticles were seen to be in uniform spherical shapes with a diameter ranging from 8 to 20 nm. SnO nanoparticles showed significant photocatalytic activity in photooxidation of bromophenol blue as the degradation efficiency reached 99.93%, and the photocatalyst exhibited the reusability as the degradation efficiency values were insignificantly changed until the fifth cycle. Antibacterial assay indicated that the synthesized SnO nanoparticles exhibit an inhibition of tested bacteria and showed a potential to be applied for further environmental and medical applications.
本研究报道了利用叶提取物生物制备花状SnO纳米颗粒。该研究聚焦于所制备的SnO纳米颗粒的物理化学特性及其作为光催化剂和抗菌剂的活性。通过X射线衍射（XRD）、扫描电子显微镜（SEM）、透射电子显微镜（TEM）、紫外可见漫反射光谱（UV-DRS）和X射线光电子能谱（XPS）分析进行表征。在溴酚蓝光氧化反应中检测了纳米颗粒的光催化活性；同时，评估了其对[具体细菌名称未给出]、[具体细菌名称未给出]和[具体细菌名称未给出]的抗菌活性。XRD和XPS分析证实了单一四方相的SnO。SEM分析结果表明SnO纳米颗粒具有花状形态，通过TEM分析，纳米颗粒呈均匀的球形，直径范围为8至20纳米。SnO纳米颗粒在溴酚蓝光氧化反应中表现出显著的光催化活性，降解效率达到99.93%，并且该光催化剂具有可重复使用性，直到第五个循环降解效率值变化不显著。抗菌试验表明，合成的SnO纳米颗粒对受试细菌具有抑制作用，并显示出在进一步环境和医学应用中的潜力。
