Hydrogen desorption mechanism in a Li-N-H system by means of the isotopic exchange technique

Thermal desorption mass spectrometry, thermogravimetric analysis and Fourier transform IR analyses were used for examining the hydrogen desorption mechanism in the reaction from LiH + LiNH2 to Li2NH + H2 by replacing LiD or LiND2 for LiH or LiNH2. The reaction of LiH and NH3 molecules result in the formation of LiNH4 molecule in the hydrogen desorption process.
