A novel Se/C nanocomposite with core-shell structures has been prepared through a facile one-pot microwave-induced hydrothermal process. The new material consists of a trigonal-Se (t-Se) core and an amorphous-C (a-C) shell. The Se/C composite can be converted to hollow carbon capsules by thermal treatment. These products were characterized by transmission electron microscopy (TEM), powder X-ray diffraction (XRD), scanning electron microscopy (SEM), selected area electron diffraction (SAED), energy-dispersive X-ray (EDX) spectroscopy, and X-ray photoelectron spectroscopy (XPS).
通过简便的一锅法微波诱导水热过程制备了一种具有核壳结构的新型硒/碳纳米复合材料。这种新材料由三角硒（t-Se）核和非晶碳（a-C）壳组成。通过热处理，硒/碳复合材料可转化为空心碳胶囊。这些产物通过透射电子显微镜（TEM）、粉末X射线衍射（XRD）、扫描电子显微镜（SEM）、选区电子衍射（SAED）、能量色散X射线（EDX）光谱和X射线光电子能谱（XPS）进行了表征。
