A LiNH2/MgH2 (1:1) complex was prepared by mechanical alloying and the effects of Ti and TiF3 on the characteristics of hydrogen storage were investigated. It was found that LiMgN and Li2NH phases exist as the main phases in the LiNH2/MgH2 (1:1) complex and that Mg (NH2)2 and NH4HF2 phases appear when TiF3 is added. The onset temperature of hydrogen desorption was reduced with increasing mill time, and the hydrogen saturation absorption temperature for the LiNH2/MgH2 complex decreased about 30°C with the addition of Ti and TiF3. Ti and TiF3 as catalysts are favorable for reducing the dehydrogenation temperature. The addition of TiF3 can also facilitate the increase of hydrogen desorption for the LiNH2/MgH2 (1:1) complex.
