Effects of various metal doping on the structure and catalytic activity of CoB catalyst in hydrogen production from NaBH4 hydrolysis

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

“…82 Y. Xia et al studied the inuence of different metalloids on the Co-B catalytic performance and found that the electron transport between dopants and Co was very important for improving the characteristics of Co-B catalysts. 83 The Co-B catalysts with Co-B-O structure also exhibited excellent catalytic activities due to ferromagnetic characteristics, which could lead to the excellent dispersion of the catalysts in NaBH 4 solution. 33,84,85 Fig.…”

The Effectiveness of Silver and Gold in Catalytic Homogenous and Heterogenous Borohydride Hydrolysis – a DFT Study

“…The catalysis can be either homogeneous, using mainly metallic ions, [18,55] or heterogeneous, using mainly metal nanoparticles. [7][8][9][10][11][12]34] In this review we focus on silver and gold catalysts -as ions and metals, the various catalysts are depicted in Figure 1.…”

“…[2][3][4] Therefore, materials that are accumulating hydrogen are needed. Metal hydrides [5] are widely studied for this purpose, and borohydride (BH 4 À ) is considered as a promising storage [6][7][8][9][10][11][12][13] material due to the very large percentage of hydrogen (27 % by weight), low toxicity and low volatility, [5,14,15] but the release of hydrogen in non-acidic media is a slow process, and a good catalyst is needed. [16][17][18] Many aspects should be considered to commercialize this procedure, such as the solubility and stability of the reagents and the product, [19,20] the stochiometric ratio between the water and the borohydride salt, and recycling of the byproducts.…”

Hydrogen Production from Morpholine−Borane by Aluminum Oxide‐Supported Pd Nanoparticles

“…Although H 2 used in hydrogen‐based energy systems has exciting features (such as clean, high energy density, high purity, and non‐toxicity), producing, storing, and transporting H 2 are still big challenges to be overcome [7] . Chemical storage of H 2 in suitable carriers is a safer method than storing it in gas or liquid H 2 tanks, which require mechanically high pressure and high cost [8] . In the recent years, nitrogen (N) and boron (B) containing chemical storage materials to bind H 2 chemically have found widespread use and application.…”

“…[7] Chemical storage of H 2 in suitable carriers is a safer method than storing it in gas or liquid H 2 tanks, which require mechanically high pressure and high cost. [8] In the recent years, nitrogen (N) and boron (B) containing chemical storage materials to bind H 2 chemically have found widespread use and application. Such compounds include ammoniaÀ borane (AB, NH 3 BH 3 ), [9] hydrazine borane (HB, N 2 H 4 BH 3 ), [10] methylamine borane (MeAB, CH 3 NH 2 BH 3 ), [11] dimethylamine borane (DMAB, (CH 3 ) 2 NHBH 3 )), [12] sodium borohydride (SBH, NaBH 4 ), [13] and ethylenediamine bisborane (EDAB, C 2 H 8 N 2 (BH 3 ) 2 ).…”
