Antimony doping to greatly enhance the electrocatalytic performance of Sr2Fe1.5Mo0.5O6−δ perovskite as a ceramic anode for solid oxide fuel cells

Solid oxide fuel cells are a clean and efficient electrochemical energy conversion device. Non-transition metal Sb is originally proposed to partially replace Mo in Sr 2 Fe 1.5 Mo 0.5 O 6− δ to improve its electrochemical performance as a ceramic anode.
