The morphology and chemical composition of SnO2/Fe2O3 composite nanowire arrays are characterized by SEM, TEM, EDX, XPS, and XRD. The results show that the SnO2/Fe2O3 composite nanowires are about 180 nm in width and tens of microns in length, and they are composed of small nanoparticles of tetragonal SnO2 and rhombohedral ɑ-Fe2O3 with diameters of 10-15 nm. The SnO2/Fe2O3 com- posite nanowires are formed by a series of chemical reac- tions.展开更多

Their microstruc- tures were characterized by scanning electron microscopy, transmission electron microscopy, selective electron diffrac- tion spectroscopy and X-ray diffraction. Results indicated that SnO2 nanotubes have a thickness of about 20―30 nm, and a diameter of about 100―200 nm. The length of the nanotubes is about 1 μm, XRD and SEDS indicated that these SnO2 nanotubes are polycrystalline.展开更多
