掺杂3 mol% LaCl3的NaAlH4试样的放氢量最大并且放氢动力学性能最好,其激活能为41.6 kJ/mol,这个值低于所报道的掺杂Ti的NaAlH4的激活能.
n properties in both the amount of hydrogen release and the desorption kinetics. The activation energy of the NaAlH4 sample doped with 3 mol% LaCl3 was measured to be 41.6 kJ/mol. This value is lower than that reported for the Ti-doped NaAlH4.
