Effect of preparation method on Co–B catalytic activity for hydrogen generation from alkali NaBH4NaBH4 solution

Properties of carbon dioxide absorption and reduction by sodium borohydride under atmospheric pressure

“…The report on the reaction between S-nitro glutathione and NaBH 4 indicated that this reaction was a NO release process [34], implying indirectly that there was no obvious reaction between NaBH 4 and NO. For the impact of O 2 , Hill [35] reported that O 2 molecule was chemically inert to NaBH 4 if there were no external constrained conditions, being similar to the interpretation of Jeong et al [36].…”

Catalytic behavior of carbon supported Ni–B, Co–B and Co–Ni–B in hydrogen generation by hydrolysis of KBH4

“…2 shows SEM morphology of the Ni-B/AC, 1Co-1Ni-B/AC, and Co-B/AC catalysts and the representative EDS result. For pure Co-B and/or Ni-B catalysts prepared by chemical reduction method, the SEM images of catalyst powders usually show similar particle-like morphology with particles having spherical shape and size of a few nanometers [22][23][24]. However, the activated carbon supported catalysts display a very different morphology due to the dispersion of Co-B and/or Ni-B on the surface of carbon support.…”

Ni–Co–B catalyst-promoted hydrogen generation by hydrolyzing NaBH4 solution for in situ hydrogen supply of portable fuel cells

“…In recent years, metal borides were studied extensively as high efficient catalysts for NaBH 4 hydrolysis, among which cobalt boride-based catalysts are the most attractive ones [2,5,7,[13][14][15][16][17][18][19]. To meet the requirements of practical applications, some other metal borides, such as nickel boride [20,21] and ferric boride [8], were also evaluated.…”
