Reactivity of the perovskite system Ca1– x Sr x FeO2.5 in topotactic electrochemical oxidation at ambient temperature

Ferroelasticity of SrCo0.8Fe0.2O3–δperovskite-related oxide with mixed ion–electron conductivity

“…For example, it was demonstrated recently that relaxor ferroelectric Na 0.5 Bi 0.5 TiO 3 is a fast ion conductor with high oxygen conductivity (Li et al, 2005). At low temperatures, the anomalous oxygen conductivity of ferrites and cobaltites is determined by the presence of microdomain texture (glass-like state), with the high density of domain walls providing the channels for enhanced oxygen diffusion (Nemudry et al, 1996(Nemudry et al, , 1998(Nemudry et al, , 2001(Nemudry et al, , 2002Nemudry & Uvarov, 2006;Zhogin et al, 2006).…”

Mechanochemical synthesis, crystal structure, and electrical conductivity of Bi2M0.1V0.9O5.5 - x (M = V, Zn, Sc, Sb, In) and Bi1.8Pb0.2VO5.4 - x metastable solid solutions

“…Sintering of solid solutions with specially formulated compositions may lead to the formation of nanostructured or microinhomogeneous grains (twins, domains, clusters) [25,26]. In ceramics prepared from MC powders of mixed oxides, the grains are always nanostructured [21].…”

Oxygen rocking aqueous batteries utilizing reversible topotactic oxygen insertion/extraction in iron-based perovskite oxides Ca1–xLaxFeO3−δ

“…It is well known that some kinds of perovskite-type oxides of A 1− x Sr x CoO 3 (A = La or Nd) show good oxygen diffusivity45 and the oxygen atoms of such compounds can be extracted and reinserted topotactically by electrochemical reduction and reoxidation in an aqueous alkaline solution67. Longo et al have reported that CaMnO 3 electrochemically undergoes extraction and reinsertion of oxygen in a strong basic solution and that this reaction can be applied to cathode materials8.…”
