We report an ethylene glycol-mediated one-pot synthesis with post-annealing treatment of uniformlydistributed TiO2 nanospheres on nanosheet-based a-Fe2O3(hematite) hierarchical flowers. The present samples were characterized by several analytical techniques including field emission scanning electron microscopy (FE-SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS) and thermogravimetric analysis (TGA). Enhancement in photocatalytic efficiency with magnetically-assisted recovery could be realized in the present TiO2/a-Fe2O3nanocomposites due to the high crystallinity of anatase TiO2 and the recyclability was resulted from ferromagnetics of hematite. © 2013 Elsevier B.V.
