Hydrothermal synthesis and structural characterisation of xTiO2–(1 − x)α-Fe2O3 mixed oxide nanoparticles

xTiO2–(1 − x)α-Fe2O3 (x = 0.0–1.0) mixed oxide nanoparticles system has been synthesized by a hydrothermal route. X-ray diffraction, Mössbauer spectroscopy and electron microscopy have been used to study the structure, morphology and substitution in the nanosized samples. Experimental evidence for the solubility limits of Ti4+ in α-Fe2O3 lattice and of Fe3+ in TiO2 structure is given.
