Abstract

Visible-light responsive bismuth pyrostannate (Bi2Sn2O7) photocatalysts with the clew-like morphology have been synthesized by the hydrothermal method. XRD, FE-SEM, BET, UV-vis DRS was used to characterize the phase structure, surface morphology, and optical properties of catalysts. When the hydrothermal time was 24 h, the prepared catalysts exhibited the best photocatalytic activity and the photodegradation efficiency of rhodamine B (RhB, 5 mg/L) was about 87% after 240 min visible-light illumination. The recycle experiments show that the prepared clew-like Bi2Sn2O7 photocatalysts possess excellent repeatability and stability.
