Abstract: Large amounts of SnO2 nanoflowers with pure composition,good morphology and excellent photocatalytic performance were successfully obtained through a simple and effective hydrothermal method. The phase analysis, morphology, microstructure, specific surface area and photocatalytic properties were characterized. The results show that the morphology of SnO2 nanoflowers are uniform and the thickness of single nanopetal is about 5 nm. The synthesized products are tetragonal rutile structure with high purity,well crystallinity and high specific surface area. The SnO2 nanoflowers possess excellent photocatalytic activity for methylene blue,methyl orange,rhodamine B,congo red. The degradation time is short and the degradation rate is high. As a photocatalyst,the prepared SnO2 nanoflowers have reusability.
