Nitrogen Anchoring Effect Triggering Improved Reversible Hydrogen Storage of Mg(BH4)2

open access: yesRare Metals, Volume 45, Issue 1, January 2026.
ABSTRACT This research uncovered the influence of nitrogen‐doped MXene Ti3CN on the reversible hydrogen storage properties of Mg(BH4)2. The Mg(BH4)2‐20Ti3CN composite began releasing hydrogen at a temperature of 80°C. In addition, the composite discharged over 8.8 wt% hydrogen at a comparatively lower temperature of 270°C, whereas the pure Mg(BH4)2 ...
