title: Origin of tunable photocatalytic selectivity of well-defined α-Fe(2)O(3) nanocrystals.
abstract: Visible-light induced degradation of an aqueous mixture containing MO and RhB on well-defined α-Fe2 O3 nanocrystals shows that MO degradation is more favorable and such selectivity on the {012} facet is greater than that on {001}. The origin of selectivity is rationalized as the inherent surface structural difference and preferential molecular adsorption.
