Nanosheet-based α-Fe2O3 hierarchical structure decorated with TiO2 nanospheres via a simple one-pot route: Magnetically recyclable photocatalysts
چکیده انگلیسی

We report an ethylene glycol-mediated one-pot synthesis with post-annealing treatment of uniformly-distributed TiO2 nanospheres on nanosheet-based α-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/α-Fe2O3 nanocomposites due to the high crystallinity of anatase TiO2 and the recyclability was resulted from ferromagnetics of hematite.
