Abstract:

 

Thermogravimetric analysis (TGA) is a powerful technique for screening boranes envisaged for chemical hydrogen storage. The demonstration is based on the use of six metal (II) chlorides (MCl2)2)_{2}) (with M as 3d-metal or d88^{8}-metal) as destabilizing agents of solid-state hydrazine borane (N22_{2}H44_{4}BH3)3)_{3}). On the basis of TGA profiles combined with derivative thermogravimetric (DTG) curves, it is shown that: e.g. (1) CuCl22_{2} is an inefficient dopant whereas it is efficient towards ammonia borane (NH33_{3}BH3)3)_{3}); (2) one of the best destabilization results is achieved with N22_{2}H44_{4}BH33_{3} doped by 10 wt{\%} CuCl22_{2}-NiCl22_{2}, the sample decomposing from 30 ∘∘^{\circ}C with greatly mitigated amounts of gaseous by-products; (3) in a few cases, the destabilization extent is so important that the doped samples could be envisaged as energetic materials. Above all, the present report shows the importance of TGA-DTG in the field of boron- and nitrogen-containing materials and the proposed protocol could be used by other groups so that literature-based comparisons are more relevant.
