A novel Ba0.5Sr0.5Co0.8Fe0.2O3−δ and CeO2 hybrid electrocatalyst for both the oxygen evolution and methanol oxidation reactions

We synthesize a hybrid catalyst of BSCF@CeO 2 -10 with superior OER and MOR catalytic properties, which can be ascribed to the stable phase structure of BSCF, enhanced OH − adsorption ability, reduced RDS energy barrier, and increased Co/Fe valence.
