Morphology controlled synthesis and characterization of Bi₂WO₆ photocatalysts

Abstract

Nest-like and multilayered-disk-like Bi₂WO₆ photocatalysts were synthesized through a hydrothermal strategy using thiourea and acetic acid as complexing agents. The nest-like Bi₂WO₆ showed excellent visible-light-driven photocatalytic performance, and it could decompose rhodamine B(RhB) within 100 minutes. This excellent performance resulted from its special microstructure and the relatively large surface area.

Keywords
