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。
Copper nitrate as a copper source and ammonia as an alkali source were prepared by microwave-assisted hydrothermal CuO-CuO nanomaterials. No soft template such as surfactant or ionic liquid was used during preparation. The phase and morphology of the product were characterized by X-ray diffraction, electron spectroscopy, field emission scanning electron microscopy and high resolution transmission electron microscopy. Control experiments show that the alkali source has a great influence on the morphology of the product. The growth of flower-like CuO was studied by time-evolution experiment. The results showed that the reaction process experienced two intermediates Cu2 (OH) 3NO3 and Cu (OH) 2.
