Preparation, Characterization and Photocatalytic Properties of Flower Like Bi₂WO₆ under Solar Light Irradiation

Abstract:

Flower like Bi2WO6 powders were synthesized via a mild hydrothermal method. Analysis of X-ray diffraction (XRD) revealed that optimal calcination temperature was believed to be 400 °C at which the photocatalyst displayed high surface area and small crystallite size. Scanning electron microscope (SEM) showed that obtained Bi2WO6 with a flower like shape, which greatly enhance the surface area of catalyst and increase the contact area with dyes. The photocatalytic activity of as-prepared catalyst was investigated using Rhodamine B as a model compound under solar light irradiation. Results showed that the prepared photocatalyst was an effective photocatalyst and exhibited high photocatalytic performance. In the presence of 1 g/L Bi2WO6, 80.76% decolorization efficiency of RhB could be achived after 150 min irradiation
