Abstract

Photodegradation of rhodamine B in the presence of H 2O 2 by visible light over α-Fe 2O 3 architectures has been investigated (see picture; left to right: 1D nanorods, 2D nanoplates, 3D nanocubes). A link between the exposed facets of α-Fe 2O 3 architectures and their photoreactivity is established, following {110}>{012} {001}.
