B-Site Super-Excess Design SrVFeMoO-Ni as a Highly Active and Redox-Stable Solid Oxide Fuel Cell Anode.

In-situ exsolution type perovskites as solid oxide fuel cell (SOFCs) anode materials have received widespread attention because of their excellent catalytic activity. In this study, excessive NiO is introduced to the SrVFeMoO (SVFMO) perovskite with the B-site excess design, and in-situ growth of FeNi alloy nanoparticles is induced in the reducing atmosphere to form the SrVFeMoO-Ni (SVFMO-Ni) composite anode. Here, with H or CH as SOFCs fuel gas, the formation of FeNi nanoparticles further enhances the catalytic ability.
