【摘要】 采用液相化学还原法,利用醋酸镍为母体,1,2-丙二醇为还原剂,氢氧化钠为pH调节剂,以表面活性剂聚乙二醇-6000(PEG-6000)为修饰剂,在1,2-丙二醇体系中合成了纤维状多晶纳米镍。通过X射线衍射(XRD)、透射电子显微镜(TEM)、选区电子衍射(SAED)对所制备的样品进行了表征。通过傅立叶红外仪(FTIR)分析初步解释了纤维状纳米镍的形成机理。更多还原

【Abstract】 As reported in this paper,fibrillar nickel nanocrystals were synthesized using nickel acetate as precursor,1,2-propanediol as solvent and reducing agent,sodium hydroxide as pH adjusting agent,and surfactants PEG-6000(polyethylene glycol 6000)as modifiers.The as-prepared Ni nanoparticles were characterized by transmission electron micrographs(TEM),selected area electron diffraction(SAED),powder X-ray diffraction(XRD)and Fourier transform infrared(FTIR)spectroscopy.The fabrication mechanisms of fibrillar nickel nanocrystals have been also investigated.更多还原
