A-site and B-site substituted lanthanum manganite perovskites were synthesized and characterized for application in two-step metal oxide redox cycles for thermochemical splitting of CO2.
Hydrogen production increases with increasing Sr content, but at a kinetic penalty; intermediate Sr levels are advantageous for solar thermochemical fuel production.
Strontium-doped lanthanum manganite perovskites show promising Mn4+/Mn3+ redox activity during two-step thermochemical CO2 dissociation for solar fuel production.
