50, 85, The catalytic effects of MnFe2O4 nanoparticles on the hydrogen storage properties of MgH2-LiAlH4, X-ray diffraction (XRD), and 40 C lower than these of ball-milled MgH2-LiAlH4 sample for each stage in the dehydrogenation process. The isothermal dehydriding kinetics and isothermal rehydrogenation kinetics results indicate that adding MnFe 2O4 to MgH2-LiAlH4 could significantly enhance the absorption/desorption kinetics of MgH 2-LiAlH4. [...]. © 2013 American Chemical Society., and X-ray photoelectron spectroscopy (XPS). The nonisothermal desorption results show that MgH2-LiAlH4 + 5 mol % MnFe2O 4 has a lower onset dehydrogenation temperature, are studied for the first time. The hydrogen storage properties and reaction mechanism are investigated by pressure-composition-temperature (PCT), differential scanning calorimetry (DSC), prepared by ball milling
