Hydrothermal synthesis and characterization of visible-light-driven Cl-doped Bi₂WO₆ nanoplate photocatalyst

抄録

Pure Bi₂WO₆ and Cl-doped Bi₂WO₆ nanoplates were successfully synthesized by hydrothermal method. The characteristic results revealed the presence of orthorhombic Bi₂WO₆ products with 200–300 nm square-like nanoplates and anionic Cl incorporated in the Bi₂WO₆ lattice. In this research, the photocatalytic activity of Cl-doped Bi₂WO₆ nanoplates was tested through the degradation of Rhodamine B under visible light irradiation. The 3 wt % Cl-doped Bi₂WO₆ exhibited higher photocatalytic activity for degradation of Rhodamine B than other Bi₂WO₆ photocatalysts.
