Title: Investigation of La_xSr_1-xCo_yM_1-yO_3-δ (M = Mn Fe) perovskite materials as thermochemical energy storage media

Abstract

Materials in the La_xSr_1–xCo_yMn_1–yO_3–δ (LSCM) and La_xSr_1–xCo_yFe_1–yO_3–δ (LSCF) families are candidates for high-temperature thermochemical energy storage due to their facility for cyclic endothermic reduction and exothermic oxidation. A set of 16 LSCM and 21 LSCF compositions were synthesized by a modified Pechini method and characterized by powder X-ray diffraction and thermogravimetric analysis. All materials were found to be various symmetries of the perovskite phase. LSCM was indexed as tetragonal, cubic, rhombohedral, or orthorhombic as a function of increased lanthanum content. For LSCF, compositions containing low lanthanum content were indexed as cubic while materials with high lanthanum content were indexed as rhombohedral. An initial screening of redox activity was completed by thermogravimetric analysis for each composition. The top three compositions with the greatest recoverable redox capacity for each family were further characterized in equilibrium thermogravimetric experiments over a range of temperatures and oxygen partial pressures. As a result, these equilibrium experiments allowed the extraction of thermodynamic parameters for LSCM and LSCF compositions operated in thermochemical energy storage conditions.

Oxygen nonstoichiometry and defect structure analysis of B-site mixed perovskite-type oxide (La, Sr)(Cr, M)O{sub 3-{delta}} (M=Ti, Mn and Fe)

Journal Article Oishi, Masatsugu ; Yashiro, Keiji ; Sato, Kazuhisa ; ... - Journal of Solid State Chemistry

The defect chemical relationships in various B-site mixed LaCrO{sub 3}-based ceramics were investigated by means of high-temperature gravimetry. The nonstoichiometric deviation, {delta}, in (La{sub 0.7}Sr{sub 0.3})(Cr{sub 1-y}Ti{sub y})O{sub 3-{delta}} (y=0.1, 0.2 and 0.3) (LSCT){sub ,} (La{sub 0.75}Sr{sub 0.25})(Cr{sub 0.5}Mn{sub 0.5})O{sub 3-{delta}} (LSCM) and (La{sub 0.75}Sr{sub 0.25})(Cr{sub 0.5}Fe{sub 0.5})O{sub 3-{delta}} (LSCF) were measured as a function of oxygen partial pressure, P{sub O{sub 2}}, at temperatures between 973 and 1373 K. The effects of partial replacement of the donor on Cr-sites were examined in LSCT. In LSCM and LSCF, effects of the partial substitution of isovalent transition metals on Cr-sites are discussed.more »« less

Oxygen-deficient ferrates with the cubic perovskite structure Sr{sub x}Y{sub 1−x}FeO{sub 3−δ} were prepared in air (0.71≤x≤0.91) as well as in N{sub 2} (x=0.75 and 0.79) at 1573 K. The oxygen content of the compounds prepared in air increases with increasing strontium content from 3−δ=2.79(2) for x=0.75 to 3−δ=2.83(2) for x=0.91. Refinement of the crystal structure of Sr{sub 0.75}Y{sub 0.25}FeO{sub 2.79} using TOF neutron powder diffraction (NPD) data shows high anisotropic atomic displacement parameter (ADP) for the oxygen atom resulting from a substantial cation and anion disorder.

An A- and B-Site Substitutional Study of SrFeO_3–δ Perovskites for Solar Thermochemical Air Separation

Journal Article Farr, Tyler P. ; Nguyen, Nhu Pailes ; Bush, H. Evan ; ... - Materials

An A- and B-site substitutional study of SrFeO_3–δ perovskites (A’_xA_1–xB’_yB_1–yO_3–δ, where A = Sr and B = Fe) was performed for a two-step solar thermochemical air separation cycle. The cycle steps encompass (1) the thermal reduction of A’_xSr_1–xB’_yFe_1–yO_3–δ driven by concentrated solar irradiation and (2) the oxidation of A’xSr_1–xB’_yFe_1–yO_3–δ in air to remove O₂, leaving N₂. The oxidized A’_xSr_1–xB’_yFe_1–yO_3–δ is recycled back to the first step to complete the cycle, resulting in the separation of N₂ from air and concentrated solar irradiation. A-site substitution fractions between 0 ≤ x ≤ 0.2 were examined for A’ = Ba, Ca, and La.more »« less

Synthesis and characterization of the double-substituted perovskites LaxSr1-xCo1-yMnyO3-delta for use in high-temperature oxygen separations.

Conference Nenoff, Tina Maria ; Ambrosini, Andrea ; Garino, Terry J

Materials in the La{sub 0.1}Sr{sub 0.9}Co{sub 1-y}MnyO{sub 3-{delta}} (LSCM) family are potentially useful as ceramic membranes for high-temperature oxygen separations. A series of LSCM samples was synthesized by solid state methods and characterized by powder X-ray diffraction, thermogravimetric analysis, and four-probe conductivity. The materials were indexed in the cubic Pm-3m space group. TGA data implied that LSCM can reversibly absorb and desorb oxygen versus temperature and partial oxygen pressure, while powder diffraction data showed that the material maintained the cubic perovskite structure. Preliminary four-probe conductivity measurements signify p-type semiconducting behavior.
Material properties of perovskites in the quasi-ternary system LaFeO{sub 3}–LaCoO{sub 3}–LaNiO{sub 3}

An overview is presented on the variation of electrical conductivity, oxygen permeation, and thermal expansion coefficient as a function of the composition of perovskites in the quasi-ternary system LaFeO{sub 3}–LaCoO{sub 3}–LaNiO{sub 3}. Powders of thirteen nominal perovskite compositions were synthesized under identical conditions by the Pechini method. The powder X-ray diffraction data of two series, namely La(Ni{sub 0.5}Fe{sub 0.5}){sub 1−x}Co{sub x}O{sub 3} and LaNi{sub 0.5-x}Fe{sub x}Co{sub 0.5}O{sub 3}, are presented after the powders had been sintered at 1100 °C for 6 h in air.
