摘　　要：以硝酸铜为铜源,氨水为碱源,通过微波辅助水热法制备了花状CuO微纳米材料。制备过程中没有使用表面活性剂或离子液体等软模板剂。利用X-射线衍射、电子能谱、场发射扫描电镜以及高分辨透射电镜表征了产物的物相和形貌。对照实验显示碱源对产物形貌有着很大的影响。通过时间演化实验研究了花状CuO的生长过程。结果显示反应过程经历了Cu2(OH)3NO3和Cu(OH)2两种中间产物。The flower-like CuO was prepared via a simple, rapid, microwave-assisted hydrothermal process, using Cu （NO3）2-6H2O as the copper source and ammonia solution as the alkali source. No soft template such as surfactant or ionic liquid was used in the preparation. The phases and morphologies of the as-prepared products were characterized by using powder X-ray diffraction （XRD）, energy dispersive X-ray spectroscopy （EDS）, field emission scanning electron microscopy （FE-SEM） and high resolution transmission electron microscopy （HRTEM）. The controlled experiments showed that the morphologies were influenced greatly by the alkali source. The time- dependent experiments were performed to study the crystal growth process. The results also showed that the intermediates of Cu2（OH）3NO3 and Cu（OH）2 were involved in the reaction.
