چکیده
Redox reactivity of La(1-x)SrxMnO3 (LSM) perovskites towards a solar thermochemical CO2 splitting (CS) cycle is investigated. The LSM are synthesized via solution combustion synthesis (SCS) method using glycine as the reducing agent. Multiple analytical techniques used for structural characterization perovskites. Thermogravimetric thermal reduction (TR) and CS cycles (in three sets: one, ten cycles) conducted to estimate amounts O2 released (nO2) CO produced (nCO) by each perovskite. Higher nO2 perovskite, compared nCO during first cycle. decreased, re-oxidation capacity perovskite improved from one three. In terms average 2 10, La0.60Sr0.41Mn0.99O2.993 (214.8 μmol O2/g·cycle) La0.30Sr0.70Mn0.99O2.982 (342.1 CO/g·cycle) observed have uppermost redox reactivity. all (except La0.88Sr0.11Mn1.00O2.980) recorded be higher than that widely studied CeO2 material.

Perovskites are attractive redox materials for thermo/electrochemical fuel synthesis. To design perovskites with balanced redox energetics for thermochemically splitting CO2, the activity of lattice oxygen vacancies and stability against crystal phase changes and detrimental carbonate formation are predicted for a representative range of perovskites by electronic structure computations. Systema...
متن کاملThermodynamic and kinetic assessments of strontium-doped lanthanum manganite perovskites for two-step thermochemical water splitting
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...
متن کاملThermochemical water splitting cycles
Two processes to effect splitting of the water molecule by means of an external heat source are competing for adoption, for the long-term production of hydrogen: high-temperature electrolysis, and splitting the water molecule through a succession of chemical reactions: a thermochemical cycle. Both processes form part of a strategy of voluntary reduction of greenhouse-gas emissions, and of alter...

High-quality Ca0.8Dy0.2MnO3 nano-powders were synthesized by the solution combustion process. The size of the synthesized Ca0.8Dy0.2MnO3 powders was approximately 23 nm. The green pellets were sintered at 1150-1300°C at a step size of 50°C. Sintered Ca0.8Dy0.2MnO3 bodies crystallized in the perovskite structure with an orthorhombic symmetry. The sintering temperature did not affect the Seebeck ...
