采用简单的一锅法合成了Ni/ZnO纳米复合材料。分别以乙二醇、锌和镍配合物为溶剂和新的前驱体制备了Ni/ZnO纳米复合材料。考察了不同反应时间和反应温度对反应的影响，以确定最佳反应条件。采用X射线衍射（XRD）、透射电子显微镜（TEM）、傅里叶变换红外光谱（FT-IR）、扫描电子显微镜（SEM）和紫外-可见光谱（UV-Vis）对Ni/ZnO纳米复合材料进行了表征。振动样品磁强计分析显示了纳米复合材料的铁磁行为，这是适合于纳米颗粒回收。通过监测铜绿假单胞菌、枯草芽孢杆菌和白色念珠菌的生长来研究所选样品的抗菌效果，其中在24小时后，在37 ℃下获得的抑制区的直径分别为约15、14和9 mm。有趣的是，铜绿假单胞菌的抑菌圈直径与常规抗生素相当。(C)2019爱思唯尔B.

A simple and one-pot glycothermal method was developed for the synthesis of Ni/ZnO nanocomposites. Ethylene glycol, zinc and nickel complexes were utilized as a solvent and new precursors to prepare Ni/ZnO nanocomposites, respectively. The effect of different reaction time and temperature were examined in order to approach to the optimal sample. The Ni/ZnO nanocomposites were characterized by X-ray diffraction (XRD) analysis, Transmission Electron Microscopy (TEM), Fourier transform infrared (FT-IR) spectroscopy, Scanning Electron Microscopy (SEM), and ultraviolet-visible (UV-Vis) spectroscopy. Vibrating sample magnetometer analysis was exhibited the ferromagnetic behavior of the nanocomposites, which is appropriate for nanoparticle recovery. The antibacterial effect of the selected sample was investigated by monitoring the growth of Pseudomonas aeruginosa, Bacillus subtilis, and Candida albicans, where, after 24 h, the diameter of the zone of inhibition was obtained to be around 15, 14 and 9 mm at 37 degrees C, respectively. Interestingly, the diameter of the inhibition zone for the Pseudomonas aeruginosa was remarkably comparable to conventional antibiotics. (C) 2019 Elsevier B.V. All rights reserved.
