Carbon‐mixed aluminum hydroxide catalyst for the hydrogen generation of aluminum–water reaction
Journal of the Chinese Chemical Society, Volume 73, Issue 1, Page 105-117, January 2026.Carbon‐modified aluminum hydroxide catalysts, particularly with graphite and activated carbon black, significantly boost hydrogen generation from the Al/water reaction. The synergistic effect of graphite in the Al(OH)3 catalyst results in a remarkable activation energy reduction and achieves complete hydrogen yield in as little as 55 seconds.
