Carbon quantum dots/BiVO4 composite with enhanced photocatalytic activity

In this study, we report the facile fabrication of a carbon quantum dots (CQDs)/BiVO4 composite with efficient photocatalytic activity. Due to the excellent upconversion photoluminescence, as well as the photo-induced electron transfer and reservoir properties of CQDs, the CQDs/BiVO4 composite exhibited superior photocatalytic performance in the degradation of rhodamine B (RhB) under the irradiation of simulated solar light. This study provides a strategy for the development of high-performance catalysts based on CQDs.
