摘要
以硝酸锌为锌源,氨水、氢氧化钠、碳酸钠为沉淀剂,利用水热法制备了氧化锌。研究了不同沉淀剂得到的相应前驱体及其水热产物晶体生长规律,借助X射线衍射仪、透射电子显微镜对产物进行了表征。结果表明,以碳酸钠为沉淀剂生成的前驱体经水热得到的是碱式碳酸锌,而以氨水、氢氧化钠为沉淀剂生成的前驱体通过水热可以得到氧化锌。其晶体生长规律分别符合不同的线性关系,并具有不同的产物形貌。
Zinc oxide was prepared by hydrothermal method with zinc nitrate as zinc source and ammonia, sodium hydroxide and sodium carbonate as precipitant. The crystal growth of the precursors obtained from different precipitants and their hydrothermal products were studied.The products were characterized by X-ray diffraction and transmission electron microscopy. The results show that basic zinc carbonate can be obtained from the precursor formed with sodium carbonate as precipitant by hydrothermal method, while zinc oxide can be obtained from the precursor formed with ammonia and sodium hydroxide as precipitants by hydrothermal method. The growth laws of zinc oxide crystals prepared with ammonia and sodium hydroxide as precipitants conform to different linear growth relationships.Their crystals have different product morphologies.
