Exploring the capability of mayenite (12CaO·7Al₂O₃) as hydrogen storage material.

ABSTRACT: We utilized nanoporous mayenite (12CaO·7Al₂O₃), a cost-effective material, in the hydride state (H^-) to explore the possibility of its use for hydrogen storage and transportation. Hydrogen desorption occurs by a simple reaction of mayenite with water, and the nanocage structure transforms into a calcium aluminate hydrate. This reaction enables easy desorption of H^- ions trapped in the structure, which could allow the use of this material in future portable applications. Additionally, this material is 100% recyclable because the cage structure can be recovered by heat treatment after hydrogen desorption. The presence of hydrogen molecules as H^- ions was confirmed by ¹H-NMR, gas chromatography, and neutron diffraction analyses
