Modulation the electronic structure of hollow structured CuO-NiCo2O4 nanosphere for enhanced catalytic activity towards methanolysis of ammonia borane

In situ encapsulating cobalt phosphide into a quasi-MOF: a high-performance catalyst for hydrolytic dehydrogenation of ammonia borane

“…In addition, the activation energy ( E a ) was calculated according to the Arrhenius equation: 29 where k is the reaction rate constant, R is the molar gas constant, and A is a constant.…”

Synergistic interface between metal Cu nanoparticles and CoO for highly efficient hydrogen production from ammonia borane

“…Recent studies have shown that some transition metal (TM) catalysts (cobalt (Co), copper (Cu), iron (Fe), nickel (Ni)) exhibit catalytic activity in the hydrolytic dehydrogenation of NH 3 BH 3 . [16][17][18][19][20][21][22][23] Among them, Cu is an abundant element and is one of the TMs with the most potential for NH 3 BH 3 hydrolysis. As the catalytic performance of single metal Cu catalysts is poor, 16,24 bimetallic or polymetallic Cu-based alloys and nanoparticles (NPs) have been extensively explored to improve the activity of Cu-based catalysts.…”

Ni0.6Zn0.4O Synthesised via a Solid-State Method for Promoting Hydrogen Sorption from MgH2

“…The three conventional systems for storing hydrogen are cryogenic liquid storage (5–10 bar, 253 °C), compressed gas storage (350–700 bar at ambient temperature), and solid-state storage [ 3 , 4 ]. For solid-state storage, hydrogen can be stored in a chemical hydride such as ammonia borane [ 5 , 6 ] or in metal hydrides such as MgH 2 , LiAlH 4 , NaAlH 4 , and other materials and is expected to have a high hydrogen capacity [ 7 , 8 , 9 ]. Nevertheless, MgH 2 is appealing because of its abundance of resources, cheapness, and high gravimetric capacity (7.60 wt.%) [ 10 , 11 , 12 ].…”
