Abstract

original image

Photodegradation of rhodamine B in the presence of H2O2 by visible light over α-Fe2O3 architectures has been investigated (see picture; left to right: 1D nanorods, 2D nanoplates, 3D nanocubes). A link between the exposed facets of α-Fe2O3 architectures and their photoreactivity is established, following {110}>{012}≫{001}.
