Abstract

Tri-octyl-amine is known for its potential to assist fabrication of metal and metal oxides nanoparticles. In this work elucidate the synthesis of magnetite-ZnO magnetic nano hybrid by simple one pot reflux method. The synthesized nanoparticles were characterized using X-ray diffraction (XRD), FE-SEM, HR-TEM, vibrating sample magnetometer (VSM), fourier transform infrared spectroscopy (FTIR) and UV–Vis spectroscopy. The X-ray diffraction results confirm the formation of magnetite-ZnO nanocomposites. IR data reveals the characteristic adsorption bands for oxide formation. Magnetic property of the prepared composite was determined by VSM. The photocatalytic activities was performed using methylene blue under UV irradiation. magnetite-ZnO nanocomposite were prepared by using one-pot reflux method with the help of trioctylamine as a solvent and hydrolysing agent. Structutral, morphological, optical and magnetic properties of synthesized nanoparticles were characterized with the help of XRD, FTIR, transmission electron microscopy (TEM), UV–Vis spectroscopy and VSM. X-ray diffraction results confirm the formation of magnetite-ZnO nanocomposites and IR data reveals the characteristic absorption bands for oxide formation. Magnetic property of the prepared composite was determined by VSM. Photocatalytic activities was performed using methylene blue (MB) under UV irradiation and absorbance of MB was found to be reduced for prepared nanocomposite when exposed for longer time.

摘要

三辛基胺以其协助金属和金属氧化物纳米粒子制造的潜力而闻名。在这项工作中阐明了通过简单的一锅回流方法合成磁铁矿-ZnO磁性纳米杂化物。使用X射线衍射（XRD），FE-SEM，HR-TEM，振动样品磁力计（VSM），傅立叶变换红外光谱（FTIR）和UV-Vis光谱对合成的纳米颗粒进行表征。X射线衍射结果证实了磁铁矿-ZnO纳米复合材料的形成。红外数据揭示了氧化物形成的特征吸附带。制备的复合材料的磁性由VSM确定。使用亚甲基蓝在紫外线照射下进行光催化活性。以三辛胺为溶剂和水解剂，采用一锅法回流法制备了磁铁矿-ZnO纳米复合材料。借助XRD，FTIR，透射电子显微镜（TEM），UV-Vis光谱和VSM表征了合成纳米颗粒的结构，形态，光学和磁性。X射线衍射结果证实了磁铁矿-ZnO纳米复合材料的形成，红外数据显示了氧化物形成的特征吸收带。制备的复合材料的磁性由VSM确定。使用亚甲基蓝（MB）在紫外线照射下进行光催化活性，发现制备的纳米复合材料暴露较长时间后，MB的吸光度降低。借助XRD，FTIR，透射电子显微镜（TEM），UV-Vis光谱和VSM对合成纳米颗粒的光学和磁性进行了表征。X射线衍射结果证实了磁铁矿-ZnO纳米复合材料的形成，红外数据显示了氧化物形成的特征吸收带。制备的复合材料的磁性由VSM确定。使用亚甲基蓝（MB）在紫外线照射下进行光催化活性，发现制备的纳米复合材料长时间暴露后，MB的吸光度降低。借助XRD，FTIR，透射电子显微镜（TEM），UV-Vis光谱和VSM对合成纳米颗粒的光学和磁性进行了表征。X射线衍射结果证实了磁铁矿-ZnO纳米复合材料的形成，红外数据显示了氧化物形成的特征吸收带。制备的复合材料的磁性由VSM确定。使用亚甲基蓝（MB）在紫外线照射下进行光催化活性，发现制备的纳米复合材料长时间暴露后，MB的吸光度降低。制备的复合材料的磁性由VSM确定。使用亚甲基蓝（MB）在紫外线照射下进行光催化活性，发现制备的纳米复合材料暴露较长时间后，MB的吸光度降低。制备的复合材料的磁性由VSM确定。使用亚甲基蓝（MB）在紫外线照射下进行光催化活性，发现制备的纳米复合材料暴露较长时间后，MB的吸光度降低。
