Flower-like Sn3O4 hollow microspheres were synthesized via one-step hydrothermal process with varying reaction temperature (120℃, 135℃ and 150℃). The crystal structure, morphology, composition, specific surface area, and optical property of the obtained products were characterized by X-ray diffraction(XRD), scanning electron microscope(SEM), transmission electron microscope(TEM), high resolution transmission electron microscope(HRTEM), automatic surface area analyzer, UV-Vis absorption spectrum, and photoluminescence spectrum (PL). The photocatalytic experiments of the as-prepared samples were evaluated by decomposing the model pollutants rhodamine B (RhB). Systematical measurements revealed that the morphology of the hollow microsphere structures was faithfully preserved as changing the hydrothermal synthesized temperature. With the increase of the hydrothermal synthesized temperature, the UV-Vis absorption peak of samples shifted from 384 nm to 365 nm and the PL intensity further weakened. Finally, the photocatalytic activity presented that Sn3O4 microspheres hydrothermal synthesized at 120℃ had the best photcatalytic performance.
