Solar-driven thermochemical water splitting using non-stoichiometric oxides has emerged as an attractive technology for solar fuel production. The most widely considered oxide for this purpose is ceria, but the extreme temperatures required to achieve suitable levels of reduction introduce challenges in reactor design and operation, leading to efficiency penalties. Here, we provide a quantitati...

Nanoparticles of lanthanum-strontium manganite were synthesized via different methods, namely, sol-gel method, precipitation from non-aqueous solution, and precipitation from reversal microemulsions. It was shown that the use of organic compounds and non-aqueous media allowed significantly decreasing of the crystallization temperature of nanoparticles, and the single-phased crystalline product ...

In this study, Strontium (Sr)-doped perovskite lanthanum manganite (La1?xSrxMnO3) nanoparticles were prepared by the sol–gel method and used as electrode materials of supercapacitors. Microstructures, morphologies, electrochemical properties samples characterized X-ray diffraction (XRD), scanning electron microscopy (SEM), a transmission microscope (TEM), Brunauer–Emmett–Teller (BET) surface ar...

In this paper, the effects of infiltration of La2NiO4 (LNO) as a mixed ionic and electronic conductor (MIEC) on the electrochemical performance of porous strontium doped lanthanum manganite (LSM) oxygen electrode of solid oxide cells, in the temperature ranges of 650-850 °C, is reported. XRD and FE-SEM results of the LNO sample calcined at 900 °C confirmed the formation of single phase LNO nano...

Complexions at the Electrolyte/Electrode Interface In article number 2100967, Thomas Götsch and co-workers reveal that a complexion is formed between yttria-stabilized zirconia electrolyte lanthanum strontium manganite air electrode during sintering process of solid oxide cells. This nanometer-wide interlayer self-limited width characterized by partial amorphization compositional gradients. It ...
