摘　　要：以ZnCl2和过氧化氢为反应前驱物,CTAB为表面活性剂,在碱性溶液中180℃反应12h,合成ZnO微米棒。利用X-射线粉末衍射(XRD),扫描电子显微镜(SEM),紫外可见吸收等手段对产物进行表征。通过扫描发现ZnO结构为具有六方纤锌矿结构,主要是由直径约在1μm左右粗细的单晶微米棒组成的花状ZnO微米团簇,并简单探讨了微米棒的组装过程。紫外吸附实验说明ZnO对有机染料,如甲基橙有催化作用,表明他们在光催化方面有潜在应用。ZnO microrods are synthesized by hydrothermal synthesis method at 180oC for 12h using ZnCl2 and H2O2 as reactants in this paper,and CTAB is used as surfactant in alkaline solution.The as-prepared ZnO microrods are shown to be phase-pure single crystallites as evidenced by X ray powder diffraction（XRD）,scanning electron microscopy（SEM） and UV-Vis absorption.The results show that the samples are belong to hexagonal crystals.And the samples are mainly consisted of single-crystal flowerlike microrods and microclusters.Further experiments exhibit favorable photocatalytic activity in organic dyestuff such as methyl orange,showing their potential applications in photocatalytic activity.
