Enhancing CO2 electrolysis performance with various metal additives (Co, Fe, Ni, and Ru) – decorating the La(Sr)Fe(Mn)O3 cathode in solid oxide electrolysis cells

An enhanced CO 2 electrolysis current density of 2.20 A cm −2 @ 1.5 V at 1123 K is achieved for LSFM electrodes using Fe catalyst rather than Ru, Ni, and Co catalysts.
