这封信描述了一种在固体氧化物燃料电池运行的初始阶段在氧化物阳极表面形成Ru纳米团簇的方法，无需额外的处理步骤即可提高阳极性能。透射电镜和X射线光电子能谱观察表明，在800 ℃暴露于氢气后，Ru纳米团簇析出到La(0.8)Sr(0.2)Cr(0.82)Ru(0.19)O(3-delta)表面，且Ru团簇尺寸稳定在
This letter describes a method for forming Ru nanoclusters on oxide anode surfaces during the initial stages of solid oxide fuel cell operation, yielding improved anode performance without additional processing steps. Transmission electron microscope and X-ray photoelectron spectroscopy observations showed that Ru nanoclusters precipitated onto La(0.8)Sr(0.2)Cr(0.82)Ru(0.19)O(3-delta) Surfaces after exposure to hydrogen at 800 degrees C, with Ru cluster size stabilizing at
