Barium carbonate as a synergistic catalyst for the H2O/CO2 reduction reaction at Ni–yttria stabilized zirconia cathodes for solid oxide electrolysis cells

BaCO₃ is primarily demonstrated as an excellent synergistic catalyst for efficient electro-reduction of H₂O/CO₂ to H₂/CO at the state-of-the-art Ni–YSZ cathodes for solid oxide electrolysis cells with YSZ electrolytes and strontium doped lanthanum manganite oxygen electrodes.
