Before the dehydriding reaction, primary AlH3 particles of size 100 nm–1 µm were thought to be covered by an oxide layer with a thickness of less than 5 nm. Both the precipitation/grain-growth of metallic Al of size 1–50 nm and an increase in 'boundary space' were clearly observed inside the particles, while the morphologies of the particles covered by the layer did not change during the dehydriding reaction. This preliminary report provides fundamental information for a further study of AlH3 as a possible hydrogen storage material.}, pages = {204004--204004}, title = {Dehydriding reaction of AlH3: in situ microscopic observations combined with thermal and surface analyses}, volume = {20}, year = {2009} }
