摘要：

We show a drastically improved gas-solid reaction between NH(3) and LiH by mechanical treatment for LiH, generating a hydrogen gas even at room temperature. The results Of x-ray photoelectron spectroscopy showed that the mechanical pretreatment was effective in reducing a hydroxide phase from the surface of LiH. It was also possible to successfully recycle back LiNH(2), which is the byproduct of this hydrogen desorption reaction, to LiH under 0.5-MPa H(2) flow at 573 K. Thus, the LiH-NH(3) system provides a recyclable H, storage system to generate H(2) at room temperature with 8.1 mass% and 4.5 kg/100 L hydrogen capacity.
