    摘要:

    主要研究氬氣氣氛下通過(guò)機(jī)械球磨方法制備的摻雜兩種稀土氧化物(由0~5mol%CeO2和Y2O3) 對(duì)NaAlH4放氫性能的影響。PCT測(cè)試結(jié)果顯示，在相同的條件下，兩種稀土氧化物引起NaAlH4的最大放氫量和平均放氫速率的規(guī)律相似，都隨著摻量的增加先增大至某一值后又開(kāi)始減小。相對(duì)于Y2O3，

    Abstract:

    The effect of two rare earth oxides (0, 0.5, 1, 2, 3, 4, 5 mol% CeO2 and 0, 0.5, 1, 2, 3, 4 mol% Y2O3) on hydrogen desorption of NaAlH4 by mechanical milling under an atmosphere of argon was studied. The PCT result reveals that increasing content of CeO2
