Photocatalytic Performance Analysis of Bi2WO6Modified with CdSe Quantum Dots in Different Solvents

Bi(2)WO(6)modified with CdSe quantum dots (QDs) was synthesized in different solvents. Among these prepared photocatalysts, CdSe-Acetone-Bi(2)WO(6)demonstrated the best photocatalytic performance as tested by degradation of Rhodamine B (RhB). Moreover, three-time degradation tests proved that CdSe-Acetone-Bi(2)WO(6)had a good photocatalytic stability. The photoluminescence spectroscopy and electrochemical test showed that the recombination of electron hole pairs of CdSe-Acetone-Bi(2)WO(6)decreased most obviously, which was consistent with the photocatalytic results.
