| 摘 要： | 为制备分散性良好的掺杂氧化锌纳米粉体,以硝酸锌、碳酸氢铵及掺杂离子的盐为原料,通过室温固相化学反应先制备出掺杂前驱物——碳酸盐。根据DSC-TGA分析结果,将其在275℃分解2h,得到掺杂氧化锌粉体。采用激光粒度分析、BET、XRD、SEM对产物的粒度、物相组成、颗粒形貌等进行了表征。结果表明:所制备的掺杂氧化锌粉体呈粒状,粒度分布均匀,晶粒度为52.35nm。

| Abstract: | For fabrication of doped ZnO nanopowders, the precursor——carbonate was prepared by solid-state reaction from Zn(NO3)2·6H2O, NH4HCO3 and additives at room temperature. Doped nano-ZnO was obtained by decomposed the precursor at 275 ℃ for 2 h. The composition, particle size, appearance and the properties of the product were characterized by means of XRD, DSC-TGA, BET and SEM. The results show that the main crystalline phase is zinc oxide with hexagonal structure, particle size distribution of doped ZnO powders is narrow and the crystallite of ZnO powders is 52.35 nm. |
