Hydrogen generation from the hydrolysis of ammonia-borane using intrazeolite cobalt(0) nanoclusters catalyst

Monodisperse nickel nanoparticles supported on SiO2 as an effective catalyst for the hydrolysis of ammonia-borane

“…6) is calculated to be E a = 34 kJ/mol ± 2 kJ/mol. This is one of the lowest activation energies reported for the catalytic hydrolysis of AB [28], although the value is 6 kJ/mol higher than that which we previously found for the 3.2 nm Ni/C catalyst [22]. The surface Ni dissolution from Ni NPs supported on SiO 2 and the reformation of Ni NPs on the SiO 2 surface may contribute to the increase in activation energy.…”

Carbon dispersed copper-cobalt alloy nanoparticles: A cost-effective heterogeneous catalyst with exceptional performance in the hydrolytic dehydrogenation of ammonia-borane

“…However, the concerns over the practical use of these high cost metals have motivated the research for the development of low cost catalyst systems in the hydrolytic dehydrogenation of AB. In this context, the recent studies have revealed that heterogeneous catalysts of low-cost 3d metals such as Fe [25][26][27], Co [28][29][30][31][32][33][34][35][36][37], Ni [38][39][40][41][42][43][44] and Cu [45][46][47][48] can catalyze the hydrolytic dehydrogenation of AB. Unfortunately, most of these low-cost catalytic systems suffer from low activity and reusability performance.…”

Selective synthesis and characterization of metallic cobalt, cobalt/platinum, and platinum microspheres

“…Unlike borohydrides, ammonia-borane solutions do not require any additional stabilization by using bases but only suitable catalyst (Eq. (1)) [1][2][3][4][5][6][7][8][9][10][11][12][13][14]. …”
