摘要：
We have achieved in situ growth of g-C3N4 quantum dots (CNQDs) on the surface of Bi2MoO6 nanosheets. Compared with pure Bi2MoO6, the CNQDs/Bi2MoO6 composite shows enhanced photocatalytic performance for the degradation of rhodamine B (Rh B) under visible light, and 5 wt% CNQDs/Bi2MoO6 nanosheet sample can reduce Rh B around 100%. The enhanced performance is due to the high specific surface area caused by CNQD loading and efficient separation of electron-hole pairs through the two-component composite system.
