【 摘 要 】

Bi2Ti2O7photocatalysts were successfully synthesized via the co-precipitation method and the solvothermal method and further characterized by XRD, SEM, BET, XPS and UV-vis DRS. Under visible light irradiation, the photocatalytic performance of Bi2Ti2O7photocatalysts were evaluated by the degradation of RhB solution. The results indicated that the as-synthesized Bi2Ti2O7photocatalyst via co-precipitation method has better photocatalytic activity than the photocatalyst prepared by the solvothermal method. The larger surface area and special morphology of the Bi2Ti2O7synthesized by co-precipitation method were responsible to enhanced photocatalytic performance.
