Abstract

NaAlH₄ was mechano-chemically synthesized with high energy ball-milling method. The effect of synthesis conditions such as milling time, H₂ pressure, chloride catalysts, and solvents was investigated to enhance the synthesis of NaAlH₄. Among the chloride catalysts, TiCl₄ showed the highest H₂ pressure decrease which means the highest NaH conversion to NaAlH₄. Furthermore, when the NaAlH₄ was synthesized with THF solvent, it exhibited the higher H₂ pressure decrease than that of sample prepared without THF solvent. This is mainly due to the synergy effect of TiCl₄ catalyst and THF solvent.
