Abstract

Abstract: Bi2 WO6 modified with CdSe quantum dots (QDs) was synthesized in different solvents. Among these prepared photocatalysts, CdSe‐Acetone‐Bi2 WO6 demonstrated the best photocatalytic performance as tested by degradation of Rhodamine B (RhB). Moreover, three‐time degradation tests proved that CdSe‐Acetone‐Bi2 WO6 had a good photocatalytic stability. The photoluminescence spectroscopy and electrochemical test showed that the recombination of electron hole pairs of CdSe‐Acetone‐Bi2 WO6 decreased most obviously, which was consistent with the photocatalytic results. Abstract : The photocatalyst of Bi2 WO6 modified with CdSe QDs in different solvents was prepared successfully. CdSe‐Acetone‐Bi2 WO6 demonstrated the best photocatalytic performance by degrading RhB. This study provides a great way to obtain stable photocatalyst.
