The solid-state ammonia borane composite gives 6.5 wt% as the H2 storage capacity. The NieCo/r-GO catalyst was syn- thesized with the electroless deposi- tion technology. The hydrolysates are mainly metaborate and borate by 11B NMR analysis. a r t i c l e i n f o a b s t r a c t Article history: Hydrogen generation from the catalyzed deliquescence/hydrolysis of ammonia borane (AB) using the Ni Received 4 February 2015 eCo catalyst supported on the graphene oxide (NieCo/r-GO catalyst) under the conditions of limited Received in revised form water supply was studied with the molar feed ratio of water to ammonia borane (denoted as H2O/AB) at 20 May 2015 2.02, 3.97 and 5.93, respectively.
