摘    要:以胶质碳球为模板、六亚甲基四胺为沉淀剂,在乙醇中溶剂热反应,再经500℃煅烧6 h制备了NiO空心球。通过X射线衍射(XRD)、扫描电子显微镜(SEM)、透射电子显微镜(TEM)、傅里叶变换红外光谱(FTIR)和低温氮吸附-脱附,对NiO的结构和形貌进行了表征。结果表明溶剂热反应时间是制备完整NiO空心球的关键因素,溶剂热反应12 h,再经空气中煅烧,可制得形貌均一的NiO空心球。所得产物是由NiO纳米粒子组装而成的具有多孔结构的空心球。同时,本文对NiO空心球结构的形成过程和可能机理进行了分析和讨论。

关 键 词:氧化镍(NiO)  空心球  胶质碳球  溶剂热

Abstract:NiO hollow spheres were synthesized by a solvothermal reaction using colloidal carbon spheres (CCS) as sacricial template and hexamethylenetetramine (HMT) as precipitating agent in ethanol,and then calcined at 500 ℃ for 6 h.The characteristics of these NiO hollow spheres samples were characterized by XRD,SEM,TEM,FTIR and low temperature nitrogen adsorption-desorption isotherms.The results show that solvothermal reaction time is crucial to the integrity of the hollow spheres.The well defined NiO hollow spheres can be synthesized through 12 h solvothermal treatment and then calcination in air.The as-synthesized NiO hollow spheres have the porous wall consisted of nanosized particles.Moreover,the formation mechanism of NiO hollow spheres is also discussed.
Keywords:NiO  hollow spheres  colloidal carbon spheres  solvothermal
