“…Hence, this achievements requires different types of elements either A or B sites with acceptor-or donor-type cations [9]. Samarium oxide Sm 2 O 3 has been reported as a good catalyst with low activation energies [10,11]. Accordingly, samarium doped materials [12] has also showed that the conversion of the Sm +3 to Sm +2 species can occurs at same time with the oxidation of the other doped materials.…”

SmBaMn 2 O 5+δ (SBMO), a novel layered perovskite compound with samarium based material (Sm +3) as rare earth doped in A-site was synthesized and processed by using dry chemistry method (solid state solution). Structural characterization of SBMO has been investigated by X-ray diffraction (XRD) and scanning electron microscopy (SEM). While, thermal and electrochemical testing were done by using thermogravimetric analysis (TGA) and current voltage measurements. The Rietveld analysis of XRD data shows that SBMO was crystallized in the orthorhombic structure with the Pmmm space group. The surface morphology images showed a porous structure which indicates that this material can be used as a potential electrode in solid oxide fuel cells (SOFCs). TGA result showed the mass loss of 0.022% for SmBaMn 2 O 5+δ which is very small and indicates that the material is very stable. DC conductivity and performance test were done at RT in air atmosphere. The performance tests have done at 800 °C and 750 °C and the maximum power density was found to be 0.4 W/cm 2 at 800 o C.

“…It was already reported that samarium oxide (Sm 2 O 3 ) is a good catalyst with high activation energy [18][19][20]. It was also confirmed that doping with Ni 3+ and Ce 3+ to SmFeO 3 resulted in a noticeable stability [21] with structure having orthorhombic symmetry with Pnma or Pbnm space groups [15,16,22,23].…”

Series of Sm1-xFe1-3xZr3xO3 (SFZO, where x = 0.0, 0.01, 0.02, 0.033, 0.05, 0.1 and 0.15), was synthesised by the solid state reaction method and sintered at 1500?C in air. X-ray diffraction (XRD) and scanning electron microscopy (SEM) were used to investigate the structure of the materials. The XRD results indicated that the pure SmFeO3 and Sm0.99Fe0.97Zr0.03O3 samples are single phase materials with an orthorhombic symmetry and Pbnm space group. The increase of Zr content (x ? 0.02) causes a phase change from single to twophase system with orthorhombic (Pbnm) and fluorite symmetry (Fm?3m). The microstructural analyses showed that the Zr4+ doping resulted in an increase of porosity in the sintered SFZO compared to SmFeO3 sample. The direct current (DC) electrical conductivity at 850?C in air was found to be 0.045 S/cm and 0.007 S/cm for Sm0.99Fe0.97Zr0.03O3 and SmFeO3, respectively, showing a significant enhancement compared to the pure SmFeO3.
