Abstract:
Ethane can be electrochemically dehydrogenated and converted into electric energy via protonic ceramic fuel cells to obtain highly selective chemical ethylene without producing carbon oxides. This novel conversion path relies on a highly catalytically active anode for promote the cracking of ethane. In responding to this requirement, a previously characterized anode material (La0.6Sr0.4)0.95Fe0.9Mo0.1O3-? (LSFM) is modified by doping with active metals (Ni and Co) at the B-site of a perovskite structure. The (La0.6Sr0.4)0.95Fe0.7Ni0.2Mo0.1O3-? (LSFNM), (La0.6Sr0.4)0.95Fe0.7Co0.2Mo0.1O3-? (LSFCM) and (La0.6Sr0.4)0.95Fe0.7Co0.1Ni0.1Mo0.1O3-? (LSFCNM) electrode materials are synthesized by the combustion method. The subsequent in situ exsolution of the FeNi, CoFe and NiCoFe alloy nanoparticles in a reducing atmosphere improves the catalytic performance of the resultant electrodes.
