Compositional flexibility in Li-N-H materials: implications for ammonia catalysis and hydrogen storage.

Li-N-H materials, particularly lithium amide and lithium imide, have been explored for use in a variety of energy storage applications in recent years. Compositional variation within the parent lithium imide,...

Bulk phase behavior of lithium imide–metal nitride ammonia decomposition catalysts

Lithium imide is a promising new catalyst for the production of hydrogen from ammonia. This study reports the use of neutron and X-ray powder diffraction to investigate the presence of ternary nitrides in lithium-imide/metal nitride composite catalysts.

Isotopic studies of the ammonia decomposition reaction using lithium imide catalyst

15N-Labelled ammonia decomposition experiments over lithium imide catalyst reveal a bulk-surface mechanism via a lithium-rich phase.
