| 摘要: 以硝酸铜为铜源，六次甲基四胺为有机碱，去离子水为溶剂，采用简捷水浴加热技术控制合成了由三角纳米片组成的蝴蝶状微结构CuO。产品的组成和形貌用XRD、EDX、场发射扫描电镜(FESEM)、TEM、HRTEM和选区电子衍射(SAED)进行了表征。结果表明CuO的形貌主要受六次甲基四胺用量的影响。随着其用量的增加，CuO的形貌经历了飞鱼状-蝴蝶状-牡丹状的递变。并对蝴蝶状CuO微结构的形成机制及形貌的演变进行了探讨。 | |

| Abstract: Butterfly-like CuO microstructures composed of triangular nanosheets were controllably synthesized via a water bath heating technique using copper nitrate (Cu(NO3)2) as copper source, hexamethylene tetramine (C6H12N4) as organic base and deionized water as solvent. The crystal structure, composition and morphology of the as-prepared products were characterized by X-ray diffraction (XRD), energy dispersive X-ray spectrometry (EDX), field-emission scanning electron microscopy (FESEM), transmission electron microscope (TEM), high resolution transmission electron microscope (HRTEM) and selected area electronic diffraction (SAED). The results show that the morphology of CuO crystals is greatly affected by the dosage of C6H12N4. With the increase in the concentration of C6H12N4, the morphology of CuO is changed from flyingfish-like, via butterfly-like, to peony-like microstructure. The formation mechanism of butterfly-like CuO microstructure and the evolution of morphology are discussed. | |
