- •
NiMgAl-layered double hydroxides derived Ni catalysts for NH3 decomposition.
- •
Catalyst of certain constitution showed high efficiency and excellent durability.
- •
Superior performance is associated with the Mg site synergism toward Ni.
- •
“Spillover effect” of surface hydrogen accounts for a higher turnover frequency.
