Synthesized BiVO4 was by the co-precipitation method for Rhodamine B degradation under visible light

Abstract Recently, BiVO 4 photocatalysts has been received much attention in field of catalysts. Because it can be used to degrade harmful organic catalysts in visible light, irradiation produces CO 2 , H 2 O and less harmful organic matter. In this study, we have successfully synthesized a BiVO 4 photocatalysts via co-precipitation method in the presence of urea and different calcined temperatures. The survey calcined temperatures as 300°C; 350°C; 400°C and 450°C. The obtained materials were characterized by Scanning electron microscope (SEM) and X-ray diffraction (XRD). The photocatalytic activity was evaluated by the photocatalytic degradation of rhodamine B (RhB) degradation under visible compact Philip lamp (40W) light irradiation. The result indicates that all samples calcined are monoclinic scheelite structure of BiVO 4 . The BiVO 4 -350°C sample performed the best in the photodegradation of RhB.
