以Sm掺杂氧化铈（SDC）为载体制备微晶金属催化剂，并将其应用于中温固体氧化物燃料电池（SOFC）阳极，研究了CH4水蒸气重整反应. Ru或Ir分散的SDC表现出高的催化活性和低的活化能，这些是该应用的潜在候选人。微晶贵金属催化剂的高分散性导致即使使用显著少量的贵金属也具有如此高的催化活性。
Steam reforming of CH4on microcrystalline metal catalysts dispersed on Sm-doped ceria (SDC) was investigated with the intention of the application to an anode for internal reforming-type solid oxide fuel cells to be operated at medium temperature. Ru- or Ir-dispersed SDC exhibited high catalytic activities and low activation energies; these are potential candidates for that application. The high dispersion of microcrystalline noble metal catalysts results in such a high catalytic activity even with a significantly small amount of noble metal.
