In this work, different morphologies of copper oxide nanostructures such as nanofibers, nanospindies, nanocones and nanobricks were successfully synthesized by microwave-assisted method. The as-prepared copper oxide nanostructure materials were characterized by various techniques, including field-emission scan electron microscopy (FESEM), transmission electron microscopy (TEM), selected-area electron diffraction (SAED), X-ray diffraction (XRD) and UV-vis absorption spectroscopy (UV). Experimental results showed that the intensity and the time of microwave irradiation, especially the intensity, played critical roles in the formation of the products. The possible formation mechanism of the nanostructures is also discussed.
在本工作中，通过微波辅助法成功合成了不同形貌的氧化铜纳米结构，如纳米纤维、纳米纺锤体、纳米锥和纳米砖。采用多种技术对所制备的氧化铜纳米结构材料进行了表征，包括场发射扫描电子显微镜（FESEM）、透射电子显微镜（TEM）、选区电子衍射（SAED）、X射线衍射（XRD）和紫外可见吸收光谱（UV）。实验结果表明，微波辐照的强度和时间，尤其是强度，在产物的形成过程中起着关键作用。还讨论了纳米结构可能的形成机理。
