Sodium alanate NaAlH4 is complex hydride material for hydrogen absorption and desorption due to good storage capacity and good kinetic under temperature pressure conditions. The samples prepared doped catalyst CeCl3 and TiCl3with NaAlH4 under argon atmosphere using ball milling and hand milling.Structural properties of sample are characterized by X-ray diffraction (XRD). Hydrogen capacity of sample is maximum 5.4 wt % which is obtained from the desorption kinetics at 250 oC using Seviert type apparatus. The rate of hydrogen desorption capacity increased with amount of catalyst.In this study, the Hydrogen desorption of NaAlH4 doped with CeCl3 and TiCl3 is systematically studied.
