Abstract: Abstract Mg(AlH4)2 nanoparticles with a particle size less than 10 nm have been successfully synthesized by mechanochemical method using LiAlH4 and MgCl2 as raw materials together with LiCl buffering additive. In comparison to Mg(AlH4)2 microparticles, Mg(AlH4)2 nanoparticles exhibit a faster hydrogen desorption kinetics and lower desorption temperature. The hydrogen desorption temperatures of the first and second dehydrogenation steps are 80 and 220 °C for the Mg(AlH4)2 nanoparticles, which are about 65 and 60 °C, respectively, lower than th...
