Hydrogen generation by the reaction of Al with water using oxides as catalysts

Hydrogen generation by the reaction of pure Al powder in water with the addition of Al(OH)3, γ-Al2O3, α-Al2O3, or TiO2 at mild temperatures was investigated. It was found that the reaction of Al with water is promoted and the reaction induction time decreases greatly by the above hydroxide and oxides. X-ray diffraction analyses revealed that the hydroxide and oxide phases have no any change during the Al–water reaction, indicating that they are...
