In the present work a nano-crystalline nickel powder is prepared by selective leaching of a rapidly solidified Al–20Ni ribbon in aqueous sodium hydroxide. Almost spherical powder particles of 50–150 nm in size consist of grains having diameters in a range of 2–5 nm. Elemental analysis shows a very high gravimetric density of hydrogen in the powder of 2.6 wt.%. Mass spectrometry reveals that hydrogen desorbs from the powder at 80–150 °C.
