Renewable energy source is wind, solar etc.
The use of hydrogen as fuel reduced eliminate the
carbon emissions. sodium alante is used to store the
hydrogen due to high capicity. The purpose of this work
is to investigate the effect of transition metal (Zr, V,
Ni) on hydrogen desorption of NaAlH4.The samples
prepared doped catalyst Zr, Ni, V and TiCl3with
NaAlH4 under argon atmosphere using ball milling and
hand milling for 30 minute. The transition metals is
improve the kinetics of the hydrogen desorption in
NaAlH4 and the rate of desorption increased with
increasing the amount of catalyst . Structural properties
were characterized by XRD. The maximum hydrogen
capacity is 5.2 wt % . Kinetic measurement was taken
