Light metal hydrides - Potential hydrogen storage materials
Hayley Woolf,Ian Brown,Mark Bowden 한국물리학회 2008 Current Applied Physics Vol.8 No.3,4
Light metal nitride phases Li3BN2 and Mg 3BN3 have been synthesised as potential hydrogen storage materials. The formation pro-cesses using boron nitride and amorphous boron have been compared, showing that boron extracts nitrogen from the Li3N and Mg 3N2reactant phases and not from the nitrogen gas. This rate limiting solid state reaction is the rst in a three step reaction sequence to formthese ternary nitrides. The sensitivity of the reactions to low levels of impurity oxygen in the ow gas caused us to develop a closed reac-tion system methodology using nickel foil capsules.
