摘要：

In this study, we report the facile fabrication of Fe2O3/CQDs nanocomposites, and investigate their effective photocatalytic activity for the photodegradation of toxic gas (gas-phase benzene and methanol) under visible light. The crucial roles of CQDs in the enhancement of photocatalytic activity of the Fe2O3/CQDs composites are illustrated.
