Synthesis of Ag, Pd-Loaded Bi2WO6 and its Photocatalytic Activities

Article Preview

Abstract:

Ag, Pd loaded Bi2WO6 photocatalyst were prepared via a photoreduction process and characterized with UV-Vis-DRS, XRD and FE-SEM. The photocatalysis experimental results indicated that the photocatalytic activity of Ag-loaded Bi2WO6 was greatly enhanced compared with pure Bi2WO6, and the content of silver has an impact on the catalytic activity of Ag-loaded Bi2WO6 photocatalyst. The loaded Ag and Pd acts as the electron receptor on the surface of Bi2WO6, which inhibits the recombination of photogenerated charge carrier between Ecb to the Evb in the Ag-loaded Bi2WO6. As a result, the reduction of electron-hole recombination decreased, which could significantly improve the photocatalytic activity.
