Title Hydrogen storage of Mg-Zn mixed metal borohydrides abstract On the basis of DFT results on the ideal amount of Zn required to dissolute into the -phase of MgBH42 space group P6122 and experimental results recently presented in the literature mixtures of -MgBH42 and ZnCl2 have been prepared by ball-milling reactive
2020-4-23Electrochemical impedance experiments also showed that ball-milling of the alloy with Co3Mo could improve the surface activity to a great extent. This can be attributed to the catalytic effect of Co3Mo which had a much closer contact with the alloy powder after ball-milling on hydrogen oxidation

From the XRD spectra of the two samples no new peaks can be observed during ball milling which indicates that no new and impurity phases can be formed at the same time. With the increase of ball milling time the grain sie decreases. The preparing method
The effects of ball milling on the hydrogen sorption kinetics and microstructure of Zr 0.8 Ti 0.2 Co have been systematically studied. Kinetic measurements show that the hydrogenation rate and amount of Zr 0.8 Ti 0.2 Co decrease with increasing the ball milling time. However the dehydrogenation rate accelerates as the ball milling time increases
Recently reaction ball milling RBM has been introduced for the preparation of hydrogen storage materials. Hydrogen absorption studies on non-stoichiometric Zr based alloys revealed that Ti 0.1 Zr 0.9 Mn 0.9 V 0.1 Fe 0.5 Ni 0.5 has fast hydrogen absorption kinetics at room temperature
