Nickel- Iron bimetallic oxide nanoparticles have been synthesized in ethylene glycol using microwave irradiation technique. The microwave assisted synthesized Nickel and iron oxide nanoparticles are combined together in 1:1 molar ratio and treated under microwave irradiation followed by calcination to get Ni-Fe bimetallic oxide. The structure and composition of nanoparticles are characterized by UV-visible spectroscopy, FT-IR, X-ray diffraction (XRD), energy dispersion spectroscopy (EDS) and transmission electron microscopy (TEM) techniques. The empirical formula of the nanoparticle is found as Ni1Fe1.6O2.9 at 500 ºC, Ni1Fe1.5O2.6 at 700 ºC and Ni1Fe2O2.7 at 900 ºC by varied reaction conditions. A maximum absorbance of 357.67 nm is observed in UV-visible spectrum. The average size of particles in all cases is found to be ~30 nm as confirmed from TEM images. Antibacterial and antifungal studies have not shown any appreciable results.

镍铁双金属氧化物纳米粒子的微波辐射合成与表征

已经使用微波辐射技术在乙二醇中合成了镍-铁双金属氧化物纳米颗粒。将微波辅助合成的镍和氧化铁纳米粒子以 1:1 的摩尔比结合在一起，在微波照射下进行处理，然后煅烧得到 Ni-Fe 双金属氧化物。纳米粒子的结构和组成通过紫外可见光谱、FT-IR、X 射线衍射 (XRD)、能量色散光谱 (EDS) 和透射电子显微镜 (TEM) 技术进行表征。通过不同的反应条件，纳米颗粒的经验公式为 500 ºC 下的 Ni1Fe1.6O2.9、700 ºC 下的 Ni1Fe1.5O2.6 和 900 ºC 下的 Ni1Fe2O2.7。在紫外-可见光谱中观察到最大吸光度为 357.67 nm。从 TEM 图像证实，在所有情况下，粒子的平均尺寸都为 ~30 nm。抗菌和抗真菌研究没有显示任何明显的结果。
