Abstract

original image

Nanorust: Fe2O3 nanomaterials with controllable crystal phase and morphology have been successfully fabricated. The γ-Fe2O3 nanorods that are enclosed by the reactive {110} and {100} facets are highly active and distinctively stable for selective catalytic reduction of NO with NH3. The picture shows the shape and surfaces and the surface atomic configurations of the preferentially exposed {110} and {001} planes.
