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

Article Abstract:

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.

Mechanism of novel reaction from LiNH2 and LiH to Li2NH and H2 as a promising hydrogen storage system

Article Abstract:

The mechanism of the hydrogen desorbing reaction from LiH and LiNH2 to Li2NH and H2, based on the experimental results, is discussed. The existence of LiH near the surface of LiNH2 is highlighted, as it is very important for the progress of the reaction at temperatures lower than 200 degrees C.
