متن کاملWater electrolysis on La1−xSrxCoO3−δ perovskite electrocatalysts
Perovskite oxides are attractive candidates as catalysts for the electrolysis of water in alkaline energy storage and conversion systems. However, the rational design of active catalysts has been hampered by the lack of understanding of the mechanism of water electrolysis on perovskite surfaces. Key parameters that have been overlooked include the role of oxygen vacancies, B-O bond covalency, a...
متن کاملTensile Lattice Strain Accelerates Oxygen Surface Exchange and Diffusion in La1–xSrxCoO3−δ Thin Films
The influence of lattice strain on the oxygen exchange kinetics and diffusion in oxides was investigated on (100) epitaxial La1-xSrxCoO3-δ (LSC) thin films grown by pulsed laser deposition. Planar tensile and compressively strained LSC films were obtained on single-crystalline SrTiO3 and LaAlO3. 18O isotope exchange depth profiling with ToF-SIMS was employed to simultaneously measure the tracer...
متن کاملMagnetization reversal and nanoscopic magnetic-phase separation in La1−xSrxCoO3
The doped perovskite cobaltite La1−xSrxCoO3 LSCO has been advanced as a model system for studying intrinsic magnetic phase separation. We have employed a first-order reversal curve FORC method to probe the amount of irreversible switching in bulk polycrystalline LSCO as a function of Sr doping, field cooling procedure, and temperature. The value of the FORC distribution is used as a measure of ...
متن کاملIn-situ Atomic-Resolution Study of La1-xSrxCoO3 Using Z-contrast Imaging and EELS
The perovskite oxide LaCoO3 has been studied over the last few decades primarily due to its two transitions, namely the transition from a nonmagnetic insulating state to semiconducting one at 80 K and the transition from semiconducting state to metallic phase above 500 K. While the transition at 80 K is believed to be due to a change in the Co 3+ -ion spin state from a low spin (t 6 2g e 0 g S=...
