Synthesis of Bi0.5Sb1.5Te3/Graphene Composite Powders
In this paper,Bi0.5Sb1.5Te3/graphene composite powders were prepared by hydrothermal synthesis method.X-ray diffraction (XRD),field emission scanning electron microscopy (FESEM) and transmission electron microscopy (TEM) were used to characterize the morphology and structure of the composite powders.As a nanocomposite phase,graphene provided plenty of charge carriers and active sites for nucleation of Bi0.5Sb1.5Te3 grains.Bi0.5Sb1.5Te3 particles aggregated and attached to the surfaces of graphene randomly.In addition,it was found that the sizes of Bi0.5Sb1.5Te3 particles varied with different content of graphene.The formation mechanism of Bi0.5Sb1.5Te3/graphene composite powders was discussed.
