Mo‐doped CeO2 Synthesized by the Combustion Method for Carbon‐Air Solid Oxide Fuel Cell (CA‐SOFC) Applications

Abstract: Molybdenum(Mo)‐doped ceria (CMO) nanoparticles were synthesized by the combustion method with three different Mo compositions: 5 wt.%, 7 wt.%, and 10 wt.%. The catalytic activity of CMO for wet gasification of carbon was studied in a fluidized bed reactor, while the mechanical and electrical properties of this material were characterized using dense sintered CMO pellets. The Young's modulus was found to increase with the Mo content; the higher value measured was 289.4 GPa for CMO with 10 wt.% Mo. Measurements … Show more

“…The electrical conductivity measurements were performed under ultra-pure air atmosphere (100 mL min -1 flow rate) and the results obtained were compared with the data reported in the literature for pure CeO 2 (ceria) and Mo-doped CeO 2 with 10 wt.% molybdenum content (CMO10) [7]. The electrical connections were made with 4 spots of silver paste (Fuel Cells Materials) and silver wires (99.99% metal basis and 0.5 mm of diameter), connecting the silver wires with the surface of the sintered disc.…”

“…In this study, we demonstrate both chemical and electrical means for achieving high‐level and reversible optical tuning in the visible–UV spectrum in mixed ionic–electronic conducting oxides, utilizing praseodymium (Pr)‐substituted cerium (Ce) oxide, Pr 0.1 Ce 0.9 O 2– δ (PCO), as a model system. Ce oxide is known to be flexible in hosting a variety of dopants from lanthanide [ 24 ] and transition metal [ 25 ] groups; thus, the tuning mechanisms of optical properties presented in this work are expected to exhibit different optical responses for the different dopant types that can even be combined in the same host lattice, allowing for a richer tunable color design gamut.…”
