Abstract: SrSnO₃@TiO₂ and SrSnO₃@ZrO₂ core-shell nanoparticles were synthesized using the modified-Pechini method by impregnating the shell material on commercial materials (core) using a polymeric resin. The formation of SrSnO₃ on TiO₂ was confirmed by Xray diffraction and infrared spectroscopy, while superposition with ZrO peaks/bands occurred making this evaluation more difficult. Micrographs obtained using field emission scanning electron microscopy and transmission electron microscopy confirmed the dispersion of the perovskite phase on TiO₂ and on ZrO₂. The methodology applied in this study is promising in the synthesis of core@shell systems, using water as solvent and a low heat treatment temperature.
