摘要
以Zn(NO3)2.6H2O为锌源,NaOH为碱液,于190℃溶剂热反应12 h,合成了菜花状氧化锌纳米粉体,采用X射线衍射仪、扫描电镜和红外光谱仪对产物的结构、微观形貌和红外光谱进行了研究。结果表明,产物属于六方纤锌矿结构的ZnO,呈规则的菜花状,粒径90~100 nm,考察了反应时间、反应温度和反应溶剂等实验条件对产物形貌和尺寸的影响。
Cauliflower-like ZnO nanopowders were synthesized by solvent-thermal method via Zn (NO3 )2 · 6H2O as the zinc source and NaOH asthe alkali liquid at 190 ℃ for 12 h. The structure,morphology and infrared spectrum of as-prepared products were researched by X-ray diffraction (XRD) , scanning electron microscope (SEM) and infrared spectrometer (IR). The results indicated that the products belonged to hexagonal wurtzite structure and were uniform with the size of 90 - 100 nm. The studies of influ- ences of experimental conditions such as reaction time, temperature and solvent on the size and morphology of as-products were carried out systematically.
