Different Temperatures

Flower-like Bi2WO6 were successfully synthesized using the solvothermal method at different temperatures and characterized by XRD, FE-SEM, and DRS. We also investigated the photocatalytic activity of Bi2WO6 for the decomposition of rhodamine B under visible light irradiation. From XRD and SEM results, the reaction temperature has significant effects on the morphologies of the samples. From DRS results, Bi2WO6 samples displayed the absorption spectrum up to the visible region and then they showed the high photocatalytic activity under visible light irradiation, as a comparison with TiO2-P25.

Facile Solvothermal Method

TiO2hollow microspheres were synthesized by a facile solvothermal method. The prepared samples were characterized by the XRD, SEM, TEM, BET and UV-vis. The results showed that the TiO2hollow microspheres offered an enhanced photocatalytic activity due to the multiple reflections of the UV light within the inner hollow structure.
