文章采用Zn（NO3）2·6H2O和氨水制备前驱物，在表面活性剂十二烷基硫酸钠的辅助下利用水热法在180℃条件下合成出ZnO微米哑铃。通过X射线衍射、扫描电子显微镜、能谱、紫外-可见吸收光谱等测试手段对产物结构和形貌进行研究，结果表明，该方法制备的ZnO样品纯度较高，为六边形微米哑铃状结构，边长约为2μm，高度约为3μm。最后进一步研究了ZnO微米哑铃的生长机理和光催化性能。

In this paper, zinc oxide （ZnO） microdumbbell was successfully synthesized by hydrothermal method using precursor zinc nitrate （Zn（NO3）2 · 6H2O） and ammonium hydroxide（NH3 · H20） with sodium dodecyl sulfate （SDS）-assisted process at 180℃. The morphological and structural observation and crystallinity of the products grown were carried out by using X- ray diffraction（XRD）, scanning electron microscopy （SEM）, energy dispersive spectrometer（EDS） and UV- Vis absorption spectra. The results showed that these pure products with the side length of ca. 2 μm and the height of about 3 μm is hexagonal microdumbbelllike crystal. The possible growth mechanism for ZnO microdumbbell and the photocatalytic performance of ZnO microdumbbell were studied at last.
