Surface ligand stabilizes interstitial hydrogen in 2D transition metal hydride

Transition metal hydrides represent an emerging class of high-efficiency catalysts for hydrogen-involving reactions but suffer from insufficient thermodynamic stability. This preview highlights an excellent example of constructing an ambient-stable two-dimensional transition hydride in which the surface ligand plays the key role.

Ligand-confined two-dimensional rhodium hydride boosts hydrogen evolutionFan et al.MatterSeptember 28, 2023In BriefWe report a ligand confinement effect to break thermodynamic restriction and for the first time realize the construction of ambient-stable 2D RhH. By using electron-attracting n-butylamino ligands to enhance the interaction between Rh and interstitial H, the formation of 2D RhH becomes thermodynamically permissible and kinetically stable.
