Aluminum Hydride for Hydrogen Storage

摘要

Hydrogen desorption reaction of aluminum hydride, AIH3, was investigated by in situ microscopic observations combined with thermal and surface analyses. Before the hydrogen desorption reaction, primary AIH3 particles of size 100 nm-1 μm were thought to be covered by an oxide layer with a thickness of less than 5 nm. The morphologies of the particles covered by the layer did not change during the hydrogen desorption reaction.
