Abstract

The hydrogen storage properties of TiZrH

1.7-1.9

doped NaAlH

prepared by ball-milling method were investigated by X-ray diffraction(XRD)

scanning electron microscopy(SEM)and Sievert's technology test. The results show that the TiZrH

1.7-1.9

doped NaAlH

has good reversible hydrogen storage capacity. The dehydrogenation capacity(mass fraction)of the sample milled for 10 h reaches to 3.0% in 40 minutes and 4.5% in 11 h at 160 ℃

0.1 MPa

indicating great improvement of the dehydrogenation kinetics of NaAlH

doped by TiZrH

1.7-1.9

. The phase structure of TiZrH

1.7-1.9

doped in NaAlH

keeps stable during the hydrogenation/dehydrogen

ation process of NaAlH

which indicates the catalytic effect of TiZrH

1.7-1.9

on improving reversible hydrogen storage property of NaAlH
