The dehydriding property of xNaBH4+ (1-x) Mg2FeH6(x = 0.10.75) is measured to investigate the effect of combining with complex hydride Mg2FeH6on reducing dehydriding temperature of metal borohydrides, which has lately been found to be effective for LiBH4. When x = 0.1 and 0.125, a single-step dehydriding reaction is observed, while in the composition range x ≥0.25, a multi-step dehydriding reaction is observed. Despite the different dehydriding process, X-ray diffraction measurements confirmed that Mg2FeH6and NaBH4began releasing hydrogen simultaneously over the entire composition range. The results also indicate that the dehydriding temperature of NaBH4is reduced by at least 150K when combining with Mg2FeH6.
