| Popis: | The small-stones-like BaSb2O6 had been successfully prepared through two-step reaction by using inexpensive Sb2O3 reactant. The effects of reaction conditions (temperature, time) on photocatalytic efficiency were researched. The photocatalytic activity of BaSb2O6 was evaluated by photodegradation of methylene blue (MB). The results showed that the decolorization rate of methylene blue was over 90% under ultraviolet lamp (500 W) beam for 40min. Its structures and morphologies had been investigated by X-ray powder diffraction (XRD), scanning electron microscopy (SEM). The results showed that XRD pattern of BaSb2O6 was consistent with standard card and morphology of BaSb2O6 was smooth close-packed state "small stones", fine particles & no agglomeration. |
