Abstract

Magnesium ferrite/hematite heterostructured hollow nanospheres were successfully fabricated via a facile solvothermal method. The products were well characterized by X-ray diffraction, scanning electron microscopy, transmission electron microscopy, high resolution transmission electron microscopy, Fourier transform infrared spectroscopy, UV-vis absorption spectroscopy and surface photovoltage spectroscopy. From the absorption edge in the UV-vis absorption spectrum of MgFe2O4/α-Fe2O3 hollow nanospheres, an optical band-gap energy of about 1.986eV was estimated. Furthermore, it was observed that the heterostructured hollow nanospheres presented a remarkable surface photovoltage response in UV and visible spectral region, which was attributed to the effective formation of chemical interface between the two crystalline phases of MgFe2O4 and α-Fe2O3. © 2012 Elsevier B.V.
