Dehydrogenation in lithium borohydride/conventional metal hydride composite based on a mutual catalysis

The dehydrogenation of LiBH4 ball-milled with hydrogenated 40Ti–15Mn–15Cr–30V alloy was investigated. It was found that there is a mutual catalysis between the two hydrides, lowering the temperature of hydrogen release from both hydrides. In the case of 1 h milled LiBH4/40Ti–15Mn–15Cr–30V with a mass ratio of 1:4, the peak temperatures of 40Ti–15Mn–15Cr–30V and LiBH4 were decreased to 195 and 390 °C, respectively, which are 77 and 50 °C lower than the respective hydride on its own.
