中文摘要:以NiCl2为镍源,乙二醇(EG)为溶剂,采用溶剂热法成功地制备了β-Ni(OH)2微米棒,制备方法简单、易行。通过扫描电子显微镜(SEM)、透射电子显微镜(TEM)、X射线衍射(XRD)、傅立叶红外光谱(FTIR)和电感耦合等离子直读光谱仪(ICP)对产物的形貌和物质结构进行了表征,证实了反应中间体是Ni-EG配合物。利用扫描电子显微镜(SEM)考察了实验参数,如聚乙二醇200浓度、反应温度和反应时间,对产物形貌的影响,结果表明一维棒状β-Ni(OH)2的形成经历了溶解-再结晶的过程。Ni-EG配合物经退火处理,可以得到由纳米线自组装的NiO微米管。

外文摘要:Using nickel chloride as nickel source and ethylene glycol (EG) as the solvent, β-Ni(OH)2 microrods have been successfully fabricated by the solvothermal method. This method is simple and facile. The morphologies and structure of the samples were characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray diffraction(XRD), Fourier transform IR(FTIR) and Inductively Coupled Plasma Atomic Emission Spectrometer (ICP). The above experimental results proved that the intermediate product was the Ni-EG coordination polymer. The effect of the experimental parameters, such as the concentration of polyethylene glycol 200 (PEG200), the reaction temperature and the reaction time, on the morphologies of the samples was investigated by using the scanning electron microscopy (SEM). The experimental results showed that the formation of β-Ni(OH)2 microrods went through the dissolution-recrystallization process. After the anneal treatment, Ni-EG coordination polymer changed into the NiO microtubes self-assembled by nanowires.
