VO2 Hollow Nano‐Reactor: Enabling Near‐Room‐Temperature and Ultrafast Hydrogen Release From α‐AlH3
Rare Metals, Volume 45, Issue 9, September 2026.ABSTRACT α‐phase aluminum trihydride (α‐AlH3) is a promising high‐capacity hydrogen storage material, but its practical application is limited by slow dehydrogenation kinetics and high reaction temperatures. This study demonstrates, for the first time, effective modulation of the hydrogen release kinetics of AlH3 by employing a hollow nanostructured ...
