摘要: This paper presents a novel surface coating to resolve the serviceability, stability, compatibility, and dehydrogenation of aluminum hydride (alane) using liquid carbon dioxide as an anti-solvent, dispersant, drying medium, inert atmosphere. The coated alane sample was characterized by SEM, XPS, XRD, FT-IR spectroscopy. agent uniformly applied on crystalline phase remained unchanged. molecules became more stable after coating. thermal stability before analyzed DSC. enthalpy increased under different heating rates, indicating stability. lower electric spark sensitivity showed improved serviceability method developed in this study may be suitable for other hydrogen storage energetic materials.
