摘 要：A new kind of Li-Mg-N material is prepared by ball milling under N atmosphere and tested for hydrogen adsorption and desorption by High Pressure Differential Calorimeter (HP-DSC) and Mass Spectra Temperature Programmed Desorption (MS-TPD). The HP-DSC results show that the hydrogen adsorption temperature can be dramatically reduced 60℃, from 220℃over pristine LiN to 164℃over Li-Mg-N. For the desorption process over the hydrogenated sample, the peak temperature decrease ca. 80℃, from 250℃over LiN to 172℃over Li-Mg-N. The TPD results are consistent very well with these HP-DSC results. All of these results above suggest that Li-Mg-N is one of the promising systems for hydrogen storage.
