Hydrogen Desorption Mechanism of Sodium Alanate Doped with different Catalyst

Dr. Jameel Khan

Abstract: A comparative study of sodium alante doped TiCl3, TiO2 TiF4 TiAl, Zr, Ni, V PbCl2, CeCl3 and Nb2O5 is to study in this paper. The object of this work was to investigate the effect of different catalyst on hydrogen desorption of NaAlH4. Experimental work was performed under argon atmosphere in glove box. NaAlH4 and different catalysts were mixture with x (1, 2, 4) wt % and were weighed in glove box. The samples were covered with a Kapton tape due to the air sensitivity. Hydrogen storage properties and mechanisms of sodium alanate with different catalyst were investigated systematically. Structural properties of all samples are observed by X- ray diffraction (XRD). XRD resulted showed the formation of Na_3 AlH_6 and NaH and no evidence of any Na containing phase. The study of kinetics of catalyst doped sodium alanate is done by PCT in temperature range between 100o ? 250o C. The Weight of desorption hydrogen storage is varies 3.5 % to 5.4 % at temperature range. Hydrogen storage capacity is increased as increasing amount of catalyst.
