Thermogravimetric analysis-based screening of metal (II) chlorides as dopants for the destabilization of solid-state hydrazine borane
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) (with M as 3d-metal or d8 - metal) as destabilizing agents of solid-state hydrazine borane (N2H4BH3). On the basis of TGA profiles combined with derivative thermogravimetric (DTG) curves, it is shown that: e.g. (1) CuCl 2 is an inefficient dopant whereas it is efficient towards ammonia borane (NH3BH3); (2)
