The Synthesis Of Bi2wo6 By Hydrothermal Process And Their Photocatalytic Activity

Bi2WO6 were successfully synthesized using EGME, GL, EG and water as solvents by a conventional hydrothermal method. They were characterized by XRD, DRS, BET and SEM and we also investigated the photocatalytic activity of these materials for the decomposition of Rhodamin B under visible light irradiation. The XRD results revealed the successful synthesis well-crystallized Bi2WO6 crystals with Aurivillius structure when EGME and EG are used as solvents. In addition, the well-crystallized Bi2WO6 crystals showed the flower-like structure. The Bi2WO6 catalysts prepared at 180 degrees C using EGME as a solvent showed the highest photocatalytic activity. The Bi2WO6 catalysts prepared at mole ratio of H2O/EGME more than 50% showed high photocatalytic activity.
