Abstract:
BiOCOOH was prepared by solvothermal method, and the Bi/BiOCOOH composite photocatalyst was synthesized by in-situ reduction of BiOCOOH with NaBH4 aqueous solution as reducing agent. The structure, morphology and optical properties of the prepared photocatalyst were characterized by XRD, FESEM, TEM, DRS and PL. The photocatalytic activity of Bi/BiOOCOOH composite photocatalyst was determined by the degradation of Rhodamine B. The influence of NaBH4 dosage was investigated. The results indicate that the Rhodamine B can be thoroughly degraded in 50 min when the dosage of NaBH4 is 25 mg. This can be ascribed to the SPR effect of Bi, which reduces the recombination rate of photogenerated electrons and holes and enhances the absorption of visible light.
