چکیده انگلیسی
The effect of Ti-doping on the dehydrogenation kinetics of lithium aluminum hydride has been investigated in this paper. For the decomposition of lithium aluminum hydride into trilithium hexahydridoaluminate apparent activation energies of 81 and 89 kJ/mol are found for the un-doped and Ti-doped sample, respectively. For the decomposition of trilithium hexahydridoaluminate into lithium hydride apparent activation energies of 108 and 103 kJ/mol are found. The differences in apparent activation energies between the un-doped and the Ti-doped sample are within experimental uncertainty, suggesting that the effect of Ti-doping on the kinetic parameters of dehydrogenation of lithium aluminum hydride, is mainly a prefactor effect.
