Abstract
Sm2Ti2O7 and Sm2Ti1.8Ce0.2O7 samples have been synthesized using a modified Pechini method. The evolution of structure and morphology under highly reducing atmosphere was evidenced using X-ray diffraction (XRD), Raman spectroscopy and scanning electron microscopy. Ceria seems to facilitate the reduction of titania, leading to the formation of orthorombic SmTiO3.
