In this study, a facile solution-based method was developed to fabricate hematite nanorods coated with ultrathin overlayer of TiO2 or AgxFe2-xO3.The core/shell nanorod structures of α-Fe2O3/TiO2 and α-Fe2O3/AgxFe2-xO3 were obtained by annealing solution-fabricated β-FeOOH nanorod arrays which were first ultrasonicated in TiO2 sol and Ag+ aqueous solution, respectively.
