Based on this, ultra-fine TiAl3 powder having the primary particle size of about 100 nm has been mechanochemically synthesized from a mixture of TiC1(3), AlC1(3) and Mg. The addition of this TiAl3 powder into Li3AlH6 clearly shows a good catalytic effect on the thermal decomposition of Li3AlH6 as expected. The use of fine TiAl3 catalyst is certainly more favorable than TiC1(3) in terms of hydrogen storage capacity as it does not produce irreversible chloride byproduct in alanates.
