Abstract
In this study, the N-doped carbon quantum dots (N-CQDs) were applied to combine with Ag3PO4 and form N-CQDs/Ag3PO4 hybrid materials with improved photocatalytic activity and stability toward organic dyes degradation under visible light irradiation. The efficiency of 2%N-CQDs/Ag3PO4 is improved by 20.8% higher than that of pure Ag3PO4 for the degradation MB and is retained fairly high levels after 4 successive recycling experiments. The improved photocatalytic activity and superior cycle performance are mainly ascribed to the N-CQDs as the electron acceptor enhanced the spatial separation of photogenerated charge carriers and inhibited the reduction of silver ions.
