摘要: BiOBr/Bi2Sn2O7 heterojunction photocatalysts were successfully synthesized by treating hydrothermal as-prepared Bi2Sn2O7 nanoparticles with hydrobromic acid (HBr). Partial reacted HBr to form the sheet-like BiOBr, and distributed evenly on BiOBr sheets. treated different concentrations of solution obtained, their structures, morphologies, optical, visible light photocatalytic properties characterized XRD, DRS, PL, SEM, TEM. The experimental results showed that improved activity under irradiation than pure Bi2Sn2O7. sample 0.08 mol/L shows best photodegradation performance rhodamine B. In addition, active species mechanism discussed in detail.
