Abstract
The reaction pathway and rate-limiting step of dehydrogenation of the LiNH 2 + LiH mixture have been investigated. The study reveals that dehydrogenation of the LiNH 2 + LiH mixture is diffusion-controlled and the rate-limiting step is NH 3 diffusion through the Li 2NH product layer outside the LiNH 2 shrinking core. This phenomenon is explained based on a model describing the major steps of the dehydriding reaction of the mixture, and related to the evidence obtained from X-ray diffraction and specific surface area measurements of the mixture before and after isothermal hydrogen uptake/release cycles at high homologous temperatures.
