A simple chemical precipitation of ceria based (Sm doped-CGO) nanocomposite: structural and electrolytic behaviour for LT-SOFCs

Abstract

Rare-earth doped metal oxide nanocomposites were become very unique and tend to show abundant performance in all types of fields such as electrochemical, photocatalytic, and biological. Gadolinium and Samarium co-doped ceria i.e., Ce1−xGd1−yO2−δ-Ce1−x Sm−yO2−δ [x = 0.2, y = 0.8] nanocomposite was synthesized by co-precipitation method for various applications. The formation of fluorite cubic crystal structure was observed and functional group analysis was revealed by XRD and FTIR correspondingly. SEM with EDAX was revealed the morphological and chemical composition analysis of the prepared nanocomposite. Impedance studies were completed at particular conditions and proved as a suitable electrolyte for low temperature solid oxide fuel cell (LT-SOFC) applications.
