| Abstract: | SnO2 hollow nanospheres were prepared by the simple heat treatment of sawdust impregnated by SnCl4 water solution in alkaline conditions.The crystallographic structure of the sample was determined by X-ray powder diffraction(XRD).The structure and morphology of these hollow SnO2 nanostructures were investigated by transmission electron microscopy(TEM) and high-resolution transmission electron microscopy(HRTEM).The formation mechanism of SnO2 hollow sphere was studied by TEM preliminarily;it indicates that m... |
