ScholarBank@NUS Repository. https://doi.org/10.1016/j.jpowsour.2006.04.005 | Abstract: | The dependence of chemical reaction between Mg(NH2)2 and MgH2 on the ball-milling conditions has been investigated. While the decomposition of the component Mg(NH2)2 resulted in gaseous products consisting mainly of ammonia, the mixtures of Mg(NH2)2-MgH2 prepared by ball-milling released H2 at temperatures as low as 65 °C. In addition, the increase in ball-milling time can effectively suppress the ammonia evolution during the thermal treatment. The conversion of the amide and hydride to imide-like structure was demonstrated by FTIR and XRD characterization. A total amount of 4.8 wt.% of H2 could be released from the investigated system. © 2006 Elsevier B.V.
