Περίληψη:
The use of fossil fuels is widely considered as the primary cause of global warming due to the
resulting greenhouse gas emissions. This has led to a pressing need to transition towards more
sustainable and environmentally friendly alternative fuels. Solid oxide electrolytic cells (SOECs)
offer an efficient way to recover CO2 emissions from heavy industry and transportation that
have been released into the atmosphere. SOECs are known for their high efficiency compared
to other alternatives. Our aim is to develop A-site deficient perovskite materials of exceptional
redox stability and tailored ionic-electronic conducting properties for efficient syngas
production in reversible solid oxide electrolysis/fuel cells, utilizing the reaction
CO2 + H2O ⇄ CO + H2 + O2. Several candidate cathode materials have been prepared, utilizing
the LSCM (La, Sr, Cr, X) formulation of perovskite oxide material, with the general formula La0.75Sr0.25Cr0.5X0.5O3-δ (X=Mn, Fe). Several B-site doping strategies in A-site deficient perovskites have also been employed, with the ultimate goal of studying the formation of
mono- or multi-metallic nanoparticles obtained after exsolution.
