A high-performance hydrogen generation system: Transition metal-catalyzed dissociation and hydrolysis of ammonia–borane

Nanoporous Gold Catalyst for Direct Ammonia Borane Fuel Cells

“…It can be safely handled at room temperature. It has been shown that hydrogen can be released from AB via catalytic hydrolysis [1][2][3][4][5][6][7][8][9][10] or thermal decomposition. [11][12][13][14] The rate of hydrolysis of AB (Eq.…”

Ammonia as a Hydrogen Source for Fuel Cells: A Review

“…Various catalysts with excellent catalytic performance have been developed [52][53][54][55][56][57][58][59][60][61][62][63]. These include noble metal based catalysts such as Pt, Ru, Rh, Pd, Pt and Au supported on alumina; combinations of Pt with Ir, Ru, Co, Cu, Sn, Au and Ni supported on carbon, Rh(0) nano-clusters [52][53][54][55][56][57]; and also non-noble metal based catalysts such as Ni and Co on alumina, and Ni and Co nano-particles, Cu/Cu2O, Poly(N-vinyl-2-pyrrolidone) (PVP) stabilized Ni, NiSiO2 and Fe-Ni alloys [58][59][60][61][62][63]. Unfortunately, most of the aforementioned catalysts, except for the magnetic Fe-Ni alloy catalyst, are difficult to use repeatedly in solution because they are in a powdery form or are supported weakly on a substrate.…”

Amineborane Based Chemical Hydrogen Storage - Final Report

“…More rapid hydrogen release was achieved without acids by using metals to catalyze the hydrolysis reaction (Equation 6.9 Hydrogen release from NaBH 4 and NH 3 BH 3 has previously been attained by metalcatalyzed hydrolysis, with Ru-catalysts 80,81 for NaBH 4 and Pt-catalysts 82 for NH 3 BH 3 exhibiting the highest reactivities. A variety of these and other potential catalysts were screened for activating the hydrolysis of 1, including Rh(0), Ru(0), Pd(0), and Pt(0)) supported on alumina or carbon; RhCl 3 , [Rh(COD)Cl] 2 , RuCl 3 , and NiCl 2 metal halides; and nano-or micro-sized metal or NiB 2 powders.…”
