Graphite-like carbon nitride quantum dot (CNQD)-modified Bi2MoO6 heterostructure with high visible-light photocatalytic activity

Abstract

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.
