Abstract
A highly active and stable catalyst La<sub>1.2</sub>Sr<sub>0.8</sub>Mn<sub>0.4</sub>Fe<sub>0.6</sub>O<sub>4−α</sub> (R.P.LSMF) decorated with <italic>in situ</italic> exsolved Fe nanoparticles was derived from La<sub>0.6</sub>Sr<sub>0.4</sub>Mn<sub>0.2</sub>Fe<sub>0.8</sub>O<sub>3−δ</sub> (LSMF) by simple annealing and applied to CO<sub>2</sub> electrolysis on solid oxide electrolysis cells (SOECs).
