摘要：

Highly uniformed polyhedral gamma-Fe2O3 nanocrystals are prepared via a flame synthesis method by directly combusting the organic solution of iron-precursor. Systematic investigations reveal that the polyhedral gamma-Fe2O3 nanocrystals are 26-facet particles enclosed by six {100}, eight {111}, and twelve {110} facets, and these 26-facet gamma-Fe2O3 nanocrystals present excellent catalytic activities associated with their polyhedral structures.
