以醋酸镍和聚醋酸乙烯酯（PVAc）的混合物为前驱体，在723 K下热处理，合成了粒径均匀、分散性好的立方氧化镍（NiO）纳米粒子。采用扫描电子显微镜（SEM）、透射电子显微镜（TEM）、X射线衍射（XRD）、拉曼光谱、紫外-可见吸收光谱和红外光谱等手段对产物的结构、形貌和晶相进行了表征。从XRD数据中鉴定出相纯的立方氧化镍形成。(c)2005 Elsevier B. V.保留所有权利。
Cubic nickel oxide (NiO) nanoparticles with uniform size around 40-50 nm and well dispersion have been synthesized using a mixture of nickel acetate and poly(vinyl acetate) (PVAc) as precursor followed by heat treatment at 723 K. The structure, morphology and crystalline phase of the nickel oxide nanocrystals have been investigated by scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD), Raman spectrum, UV-visible absorption spectrum and FT-IR. TEM images showed that the nickel oxide nanoparticles have hexagonal structure with uniform size distribution around 40-50 nm. Phase pure, cubic nickel oxide formation was identified from the XRD data. (c) 2005 Elsevier B.V. All rights reserved.
