Zn-MOF-74-derived graphene nanosheets supporting CoB alloys for promoting hydrolytic dehydrogenation of sodium borohydride

The mechanism and challenges of cobalt-boron-based catalysts in the hydrolysis of sodium borohydride

“…The results presented that graphene-based materials can increase the active surface area, thus improving the catalytic characteristics of Co-B catalysts. 123,124 Besides, like graphene, graphene oxide (GO) has good distribution and stability and is also an ideal support material. 125 The interface interaction between GO and Co-B catalysts could improve the catalytic characteristics of Co-B catalysts supported on GO because of the more active regions on the surface of GO.…”

Carboxylate trapping engineering to fabricate monodispersed dual-atom iron sites for efficient oxygen reduction

“…5a, all isotherms belong to type IV with the H3 hysteresis loop. [54][55][56][57] Based on the shape of N 2 sorption isotherms, there is the formation of micropores, certain mesopores, and macropores in all samples. The total specific surface area (S total ) of all nFeNC-OAc catalysts is almost the same (656-676 m 2 g −1 ), indicating that the addition of a Fe source does not show an obvious effect on the specific surface area (Table S2 †).…”

Uniform dispersion of ultrafine ruthenium nanoparticles on nano-cube ceria as efficient catalysts for hydrogen production from ammonia-borane hydrolysis

“…[7][8][9][10] Therefore, there is a crying necessity to develop a safe and effective technology for producing/storing hydrogen, especially for hydrogen-oxygen fuel cells with higher energy density to power portable tools and equipment. Some solid hydrogen storage materials can react with water to produce hydrogen at room temperature, [11][12][13] which is a convenient, economical, efficient, and feasible way to supply hydrogen to small hydrogen-oxygen fuel cell systems. Ammonia-borane (NH 3 BH 3 , AB) is one of the most important chemical hydrides due to its high hydrogen capacity (19.6 wt%), non-toxicity, excellent solubility in water, and superior solid phase stability at room temperature.…”
