Destabilized and catalyzed borohydride for reversible hydrogen storage

摘要

A process of forming a hydrogen storage material, including the steps of: providing a borohydride material of the formula: M(BH4)x where M is an alkali metal or an alkaline earth metal and 1≰x≰2; providing an alanate material of the formula: M1(AlH4)x where M1 is an alkali metal or an alkaline earth metal and 1≰x≰2; providing a halide material of the formula: M2Halx where M2 is an alkali metal, an alkaline earth metal or transition metal and Hal is a halide and 1≰x≰4; combining the borohydride, alanate and halide materials such that 5 to 50 molar percent from the borohydride material is present forming a reaction product material having a lower hydrogen release temperature than the alanate material.
