摘要
在聚乙烯吡咯烷酮存在的条件下,用水合肼还原硝酸银,通过控制反应条件成功制备出了粒径均一、有良好分散性的银纳米微粒,并以此为种子,利用种子诱导生长,在十六烷基三甲基溴化铵的棒状胶束环境中制备出了银纳米棒和纳米线.并用X射线衍射、透射电子显微镜、傅立叶红外光谱和紫外-可见光谱等手段对产品的形貌、结构进行了表征.
In the presence of PVP, silver nanoparticles with narrow size distribution and fine dispersion are synthesized by reduction of silver nitrate with hydrazine solution. With the above Ag particles serve as seed, Ag nanorods and nanowires are successfully prepared, in the presence of rodlike micelles of hexadecyhrimethyl ammonium bromide. The products are characterized by X-ray diffraction, transmission electron microscopy, Fourier transform infrared spectroscopy and UV spectra.
