Abstract

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.
