摘要：

以六水合硝酸锌和脲为原料,经水浴加热,高温煅烧,获得具有蒲公英状的氧化锌.通过X射线粉末衍射仪、扫描电子显微镜、透射电子显微镜和BET对氧化锌的结构和形貌进行了表征,以及采用紫外漫反射仪对氧化锌的紫外吸收进行了测定,并研究了所制备的氧化锌对溶液中罗丹明B的光催化降解性能.实验结果表明:制备的氧化锌具有分级结构,对罗丹明B具有较好的光催化性能,光照反应1h,对罗丹明B(1.0×10-5 mol/L)的降解率达98.97%.

Zinc oxide with dandelion shape were obtained using zinc nitrate hexahydrate and urea as original materials through water bath reaction and calcination afterwards. The product was characterized by XRD, SEM, TEM and BET analyses to observe its morphology and structure. We conducted ultraviolet diffuse reflectance measurement to study the UV absorption of the ZnO product. And the photocatalysis behaviourof ZnO obtained was studied by the RhB degradation experiment. The characterizations reveal that the obtained ZnO showed dandelion shape, and exhibit efficient photocatalysis performance with a degradation rate of 98. 97% of RhB（1×10^-5mol/L） after 1h＇s UV illumination.
