Abstract

The effects of Ni and Co addition on the hydrogen storage properties of Mg3Mm alloy was studied by X-ray diffraction (XRD), scanning electron microscope (SEM), energy dispersive X-ray spectroscopy (EDX) and pressure-composition isotherm (PCI) measurement. The hydrogen absorption kinetics and the thermodynamic parameters (apparent ΔH, ΔS) for Mg3Mm dehydrogenation reactions in Mg3Mm, Mg3MmNi0.1and Mg3MmNi0.1Co0.1alloys have been also investigated. The maximum hydrogen storage content of Mg3Mm, Mg3MmNi0.1and Mg3MmNi0.1Co0.1alloys was improved due to that the addition of Ni and/or Co further spurred the MmH3phase transforming to MmH2phase. On the other side, the kinetics curves show the addition of Co could enhance hydrogen absorption rate while the addition of Ni change the hydrogenation reaction mechanism.
