Synergic Effect

CdS/Ag2S/g-C3N4 ternary composites showed excellent photocatalytic performance toward H2 evolution. Their improved photocatalytic activity could be attributed not only to the synergic effect, but also to the introduction of Ag2S.

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.
