摘要: 以碳球为模板,高锰酸钾为锰源,成功地制备了粒径较为均一的二氧化锰球壳,通过透射电子显微镜(TEM)、扫描电子显微镜(SEM)、X射线粉末衍射(XRD)等手段对合成产品进行了表征,并考察了不同合成条件对空心球的影响。结果表明,合成的二氧化锰空心球粒径均一,壁厚可调。

Abstract: MnO2 hollow spheres were successfully prepared using carbon spheres as template and permanganate as manganese source.The samples were characterized by transmission electron microscopy(TEM), scanning electron microscopy(SEM) and Xray diffraction(XRD). The experimental results show that the MnO2 hollow spheres have tunable shell thickness and uniform shell.
Key words: MnO2; template; hollow spheres;carbon spheres
