Preparation, Characterization and Photocatalytic Properties of Ag-Loaded Bi₂WO₆

Abstract:

Ag-loaded Bi₂WO₆nanoparticles were prepared by hydrothermal method. The products were characterized by XRD, UV-vis DRS, SEM and BET. The results indicated that it was the orthorhombic phase of Bi₂WO₆ and showed a markedly blue-shift Compared with pure Bi₂WO₆. Ag/Bi₂WO₆photocatalysts exhibited obviously enhanced photocatalysis than pure Bi₂WO₆ in degrading phenol-containingwastewater under visible light irradiation. The influence of the content of silver on the photocatalyticactivity of Bi₂WO₆ has been investigated. The resultsrevealed that the significant enhancement of photocatalytic activity can beattributed to the synergetic effects between noble metal and semiconductor component.
