固相合成纳米NiO微粒

Solid-phase synthesis of NiO nanoparticle

以NiSO4 ·7H2 O和NaOH为原料 ,用固相法合成了NiO纳米微粒 .研究了不同焙烧温度及同一温度下不同焙烧时间对NiO纳米微晶的晶化过程的影响 .用X射线衍射、透射电镜、热重、差热分析等方法研究了样品的性能 .结果表明 ,固相法可以制得平均粒径为 5nm的NiO纳米微粒 ,属六方晶系 ,形状为球形 .

Nano sized NiO was synthesized by solid state reaction between NiSO 4·7H 2O and NaOH.The crystal structure,particle size,and morphology of NiO nanoparticles were examined by XRD,TEM,and TG睤TA techniques.The results indicates that the spherical NiO nanoparticle is hexagonal crystal with an average diameter of 5?nm .
